I'll be ordering my new system monday and it will be composing of... Intel Core i7 920 OC 3.6ghz, 6GB 3x 2GB Corsair Dominator 240-Pin DDR3 SDRAM DDR3 1600, CORSAIR CMPSU-1000HX 1000W, Asus P6T Deluxe, and a Antec Twelve Hundred case. I've always been an nVidia fan and this will be my first time leaving nVidia if I went with the ATI HD 4870 X2. I'm looking at getting two of the XFX, or eVga, or BFG GTX 260 216 Core cards that are OC'd quite a bit. Two of any of those or one of the HD 4870 X2. How much of a performance gap is there between these two options? Or are they pretty much equal? I've tried researching benchmarks regarding these two options but have yet to find any reliable ones. -Thanks
