I would recommend you buy a 750W PSU just to be safe, since I'm guessing you're going to be Crossfiring. Also I would recommend you to wait until mid 2012 if you can wait, since the new "Ivy Bridge" Intel CPUs will release and if it fits your budget, you can buy that or if it doesn't the "Sandy Bridge" CPU is bound to drop in price

With that Radeon 6970, I've heard that you should get at least a 850w PSU for Crossfire.
And just to let you know, that card is a three slot card and Crossfiring two of them might not fit.
 
1. Why Z68 ? I know it's the latest and greatest but will you be taking advantage of any of its benefits ? If not, that opens more options. Read the Z68 section here:

2. If not doing rendering, CAD, video editing or anything else that uses HT, drop tot he 2500k which will run substantially cooler.

3. Id take the Cuda over the Black

4. Starting w/ a single GPU means you considering a 2nd.....PSU a bit small for that and what I'd buy would depend on the resolution....at 2560 x 1600, Id get the 6970 .... at 1920 x 1200, I get the 900MHz 560. That single 6970 at $380 is not that much cheaper than twin 560's in SLI....the twin 560's will boost performance 64%

Guru3D uses the following games in their test suite, COD-MW, Bad Company 2, Dirt 2, Far Cry 2, Metro 2033, Dawn of Discovery, Crysis Warhead. Total fps (summing fps in each game @ 1920 x 1200) for the various options in parenthesis (single card / SL or CF) are tabulated below along with their cost in dollars per frame single card - CF or SLI:

$ 380.00 6970 (526/825) $ 0.72 - $ 0.92
$ 230.00 560 Ti - 900 Mhz (495/862) $ 0.46 - $ 0.53

You'll note that two 560's outperform two 6970's by 5% at 1920 x 1200 and they do it for 60% of the price

http://www.newegg.com/Product/Product.aspx?Item=N82E16814121425

Again, at 2560 x 1600, Id take the 2GB 6970's

5. PSU - 650 too small for adding that 2nd GFX card later. For the same $85 ya can get the XFX Core Edition 750 which gets the exact same 9.5 jonnyguru performance rating as the TX650 V2. The 850 watter is $5 more

http://www.newegg.com/Product/Product.aspx?Item=N82E16817207015
http://www.newegg.com/Product/Product.aspx?Item=N82E16817207011

Ya can save $95 with no impact on gaming poerformance with the CPU change.
Ya will spend $15 more for the Cuda this week for more perfomance.
Ya will spend $80 more for the twin 560's for a 64% increase in performance
PSU is a wash

So for same exact price, gaming up 64% and storage up a bit, and ya PSU can handle twin cards

Thanks, folks.

Would not want to wait until mid 2012 for the next generation - Ivy Bridge. Where do you draw the line for holding back?
I never upgraded in the past, so not likely to add a second GPU, more likely to replace when time (and money) comes.
No one seems to be concerned with the 650W feeding a single 6970 system - and that's reassuring.
Why Z68? SSD caching, and other mature features combined from P67 & H67. Makes sense?
JackNaylorPE, can you please include a link to the (1) Guru3D GPU cost per frame comparison table, and (2) jonnyguru PSU performance comparison table?

"Ivy Bridge" is rumored to come out in March of 2012, while at latest in mid 2012. I would wait for the technical specs and see if it really is way better than "Sandy bridge". If it is, you might want to go with the "Ivy bridge" CPUs. If they aren't and you want to still go with the "Sandy bridge" ones, you'll know for certain that they will drop in price.
