Hey guys I have the money to invest in a nice GPU setup, I am coming from just a single HD 6870 BE and selling it to a friend and I am wanting a nice gaming setup for my ASUS 24'' LED @ 1920x1080p. I have funds upto $700 as my budget. Should I get two good cards and sli/xfire or stick with just getting a single card? If you guys can hook me up with some really good ideas if possible. Something that would keep me not needing an upgrade in sometime would be great, and not needing to have to worry about upgrading for any new games for a bit. I have an i5 2500k @ 4.6Ghz + Corsair H80 Liquid Cooling, 8gb ddr3 1600mhz, Corsair TX 750W V2 80 plus bronze certified, Gigabyte UD3H-B3 Z68X Motherboard. Thanks!
