I haven't decided if i am going SLI or Crossfire. I have always been partial to nVidia graphics cards, mostly because they are Linux friendly and I like to play with Linux from time to time.
Right now I do have a linux desktop and a linux laptop so I may be looking at ATI cards again for this rig. It is going to be performance that decides it for me......ater years of buying hardware on the cheap, i am finally able to spend the money I want to for a rig that will last for years, instead of months.
I think I will be getting a Corsair 1200w psu to handle everything I am going to put in this thing but am still on the fence about my gpu. I am looking at the GeForce GTX 560 but will listen to arguments for others. Battlefield 3 is coming out soon and I need to be ready!!
