Re: AREA 51 Best Video card with i975X?
Dell has this page
I would recommend just upgrading to a single graphic cards, ATI or Nvideo as you like.
For Battlefield 3 the lowest card i recommend is GeForce GTX 560 or Radeon HD 6950. and more video memory the better.
For the rest of your system , what Tesla said.
One warning. The very high end video cards on that motherboard have some problems with Battlefield 3 on 64 player maps. Fix is to turn down the texture settings to match the video memory.
Battlefield 3 is more dependant on the video card and video card memory than on the CPU or main memory.
