Umm, isn't that pretty much exactly what I described in my OP? Albeit I didn't use the phrase "dynamic overclocking".
Maybe? Perhaps? Depends? :p
Doesn't matter now ;)

If the photos are on the SSD drive, then yes they will launch faster than if on the HDD. Now that said, if they are just average say 2MB JPG photos the difference will not be huge. If it is a very hi-res photo say 10MB JPG the difference will be more noticeable.
Makes sense . . thanks
edit: just read this article which explains it quite well

So I'm a freelance Editor/Motion Graphics guy with no real understanding of RAID Controller Cards, or how they work.
As of right now I have three 1TB drives inside my Mac Pro, RAIDed together (stripe 0) using the OS. No Raid card.
The drives are all 7200rpm from varying manufacturers. (not sure if this matters.)
My questions is; is it beneficial for me to get a RAID card to control these drives vs. leaving it to the OS to handle? Any suggestions for me?
Thanks.

It all depends on the details of how you use the system (RAID is supposed to be configured to the specific usage, so there's no "one size fits all", though for narrowed usage patterns, you will see similarities).
I'd advise you to search out previous RAID threads (there's quite a few), and pay attention to the various questions asked, and get back to us with some answers). I'd also recommend you review Wiki's RAID page (http://en.wikipedia.org/wiki/RAID) (pay particular attention to the different levels).
If you're a paid professional, using a stripe set (RAID 0) is a disaster waiting to happen. Even with a backup, you'll spend a fair bit of time to perform a recovery when a disk dies (matter of when, not if), and this also means re-performing work that was done between the most recent backup and when the array failed (beyond replacing the bad disk and restoring all the backup files, which presumably <worst case>, will be multiples to return all the data you have from your backup media).
Glad to see you at least have some sort of backup with your current configuration. :)
Now if you go with a RAID card, you'll need to use enterprise grade drives for stability reasons (different recovery timings in the firmware than consumer models, which tend to be unstable as a result). Unfortunately, they're not as cheap (in fact, can be 2x as expensive as their consumer counterparts for the latest capacity).
Consumer disks are fine for backup purposes though, and this can save you a considerable amount of funds, particularly if your capacity requirements are high (i.e. eSATA card + Port Multiplier based external enclosure; example kit (http://www.newegg.com/Product/Product.aspx?Item=N82E16816111136&cm_re=tr4mp-_-16-111-136-_-Product)).
There are some inexpensive products that claim RAID 5, but be careful. Some are software based, which should never be used for this level (no solution to the "write hole issue" associated with parity based arrays). Others use very inexpensive hardware RAID controllers (aka RoC = RAID on a Chip). They're slow for primary usage, and is why they're cheap (compromise on performance vs. proper RAID cards).
If on a budget you could go with RAID-Z, it involves switching to the ZFS file system. RAID-Z1 apparently offers similar performance to RAID5. Read this thread (http://forums.macrumors.com/showthread.php?t=1135718) for further insight.
This can get complicated on the software end though, and not recommended for those that aren't comfortable with the additional complexity (patches for OS X or via VM), particularly for a DAS system (has more merit with NAS or SAN IMO).
So I'd stick with a 3rd party hardware RAID card, assuming this is actually needed, enterprise disks and any enclosures/mounting hardware necessary. Much simpler in terms of software (install the drivers, and any interface software that's required to access the card settings), and the hardware aspect isn't that difficult either.
I would get an SSD for the OS and use the 3x 7200rpm Disks in RAID5.
RAID5 is great for storing uncompressed video data and in your case would offer protection against a single drive failure.
Most cards don't deal with consumer grade disks very well (ATTO and Area definitely don't).
But consumer disks are fine for backup purposed (i.e via eSATA and PM enclosures) due to the lower duty cycle (where you can cut costs effectively, and not endanger the data).
or Just RAID5 with 3x HDD's and partition the RAID volume.
I wouldn't do this if both partitions are to be used simultaneously (i.e. primary data one one partition, scratch data on the other).
The most recommend cards right now are the Areca 6g 1880 series or the new ATTO 6G series. For your needs something like the ARC-1880-i SAS 6G RAID Controller would suffice if you don't plan to connect external RAID/Storage solution.
Those are the best recommendations as far as brand and series per. As to a specific model, it will depend on the specifics, particularly for growth (i.e 8 ports may be outgrown in under 3 years, so getting a card with sufficient ports to last that long would be cheaper in the long run - just add disks and enclosures as necessary).
Sorry should have been more clear (like I said I'm dumb) I have a 500GB Boot drive that lives independently from the (3) 1TB drives RAIDED together via the OS.
A separate boot disk is advisable, as you still have a working OS if the array goes down (allows you to access the card, use the browser to search for help, or deal with Support from the card manufacturer if needed).
And ALL data (3.5TB's) is backed up by an external 4TB Time Machine RAID (2 drives @ 2TB each)...which is connected via 2 eSATA cables via the eSATA PCI Card I bought from OWC...which I guess is actually RAIDed by the OS as well.
That backup solution is a RAID 0. The overall backup solution will almost certainly need to change in order to be sufficient for the primary storage pool you'll end up with.
Not sure what you are looking at, since 3 drives is sort of an odd combination. I have a 2009/2010 Mac Pro Nehalem, running the apple sas card for the 4 internal bays (yes I know they make adapters to use 3rd party cards), and the performance is fair, not great but fair. About 300Mb/s read/write with 4 WD Black edition drives (1tb each). Externally, running an Areca 1680x card, with a 8 drive ProAvio chassis, 8 SAS Seagate 15k7 drives (450GB) which gives close to 900MB/s. I have tried multiple cards over the years, nano and I have exchanged lots of posts/messages. Email/PM me with specific questions and I will try and help you. Beware of most of these 3rd party slot adapters/etc. they are more hassle than they are worth.
I've not heard or seen any issues with the MaxUpgrades kit.
As per Apple's card, I'm no fan of it, particularly due to the cost/performance ratio.
BTW, the OP only has 2 posts at the time of writting this, so returning a PM isn't possible yet (needs to have 5 posts IIRC). email would work if you have that enabled.

How are you plugging them in? If you can get the guitar to work, every thing else should. You should plug the line out from your keyboard to the audio inputs of your tascam. For the mic, it should go into the mic in.
As for returning it, it's not a bad idea. It sounds as though you just plugged things wrong if you can get it to record your guitar. But tascam interfaces are a pain in the ass. Really, I had the L version of the interface and it wouldn't work when I wanted it to. I had to reinstall the drivers countless times, plug and unplug it, restart my computer. And apparently, I'm not the only one to get all of those problem, there's a thread about in the board. They never release new drivers and usually the updates aren't that better. I just hope I can save you the trouble.

A lot of the times if you don't properly drive a high impedance can, a lot of its sound won't be as tight and crisp as it should, so it's not just the volume output. I remember the first time I heard a high quality tube amp on a HD650 in a store, it was the first time it made a song I really know and like have a bass that sounded like an actual kick drum rather than a soft boom boom noise, I was pretty amazed.

The Zalman has a back that fully encloses the fans. From the pics, the CoolerMaster does not. My experience with another design that did not enclose the fans was that the wiring eventually got snagged on something and the fans no longer received power as a result.
I think you'd be pleased with the Zalman's build quality. I know I am.

GodFather has been getting ok reviews but is basically the PS2 game with a bit of waggle
Cooking Mama - has been getting 'AWFUL' reviews
Blazing Angels - has sucked the ass on all formats - wii is meant to be no different.
Ouch! That sucks!
Hows the port for TD:U for PS2 (besides graphics)? Is there anything they took out of it, like the MMO racing feature or only racing half the island? I don't see any reviews for the ported game yet. :o

If you're willing to spend that much then why not just get a baseline 2011 MBP?
The Intel i series of the new MBPs will be far better than that C2D found in that macbook. See here (http://store.apple.com/us/browse/home/shop_mac/family/macbook_pro?mco=MTM3NjU5MzU)

It was originally 250 and it was one that was up for the 100 dollar rebate. When i ordered it the website said that it was on back order adn that it would probably take 6 weeks to get here, which did not bother me seeing as i did not need it right away.
I just called them and they said it was discontinued and that they no longer carried it. Meaning that i ordered a printer 5 weeks ago that in the end would never get here. I am peeved because when i ordered the printer it was not discontinued. And while there are some other printers availible they are not the ones that i want!! I want the one i ordered 5 weeks ago.
Apple should at least honor the orders that were mad for that printer before it was discontinued!!Seems to me that the reason the printer was originally on backorder was that it HAD been discontinued (by the manufacturer), but Apple didn't know that yet... all they knew was that they were out of stock and that the product was backordered for that reason. As soon as they found out that no more printers would be available, they e-mailed everyone who had the printer on backorder and let them (and you) know that it would not be available.
Tough break, but you can't expect Apple to conjure a printer for you out of thin air. Perhaps they will give you a comparable rebate on a similar printer, but they're under no obligation to.
