First off, thanks again for the feedback ahead of time as I've never been steered wrong from this great community!
My build is for game design (3ds max, visual studio pro 2010, etc.) and for gaming. I plan on purchasing within the next month after taxes get back or maybe a little later if I decide to wait on grant re-embursment. I know nvidia is getting ready to release the new cards soon and prices will drop but if its not in my time frame I'm not too worried about it as the build should last a few years. My question is if you were me, would you stick with the current chosen GPU or go with a pair of :
EVGA SuperClocked 01G-P3-1563-AR GeForce GTX 560 Ti (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
From the charts I was looking at the 2 cards would be better and price wise wouldn't be but about $50 more after mail in rebates. But as for what I'm doing would the cards be worth it. Each having 1GB vs the single card with 2560MB and then down the road I could upgrade to the Keplar or w/e is the best bang for the buck in the upcoming few years.
I faced a similar dilemma in regards to the GPU. I opted for the GTX 570 2.5GB for the ability to SLI later. Card works great in my system. Most of your parts are, for the most part, similar to my build. Only suggestion is perhaps getting low profile memory instead of memory that has a heat sink - your CPU fan is quite large and may cause a spacing issue.
