modified a little bit of original build: Mobo
ASRock P67 EXTREME4 (B3) LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard
Personally, i king of like the evga oc gtx 560 ti, especially since i can always buy 2 more later since my mobo supports 4...would maybe have to buy a new case too, but oh well
and a power supply too
That asrock extreme4 supports dual cards in x8, and tri cards in x4. So two cards is the max you want to go with that board. But dual gtx 560ti's in SLI is plenty of gpu power imo. A tri card set up is a heat magnet not to mention you run into problem with stuttering.
For a tri card set up, you would want a NF 200 board like this own down below that comes out in the next week or two.
yeah, i'm going to go with the msi twin frozr II 2 gb hd 6950, since I like the non-stock fans they have, and you can still sometimes flash the bios, but I doubt i'll do that for a few years, especially since I'm going to have 2
