Video card question

[N8DOG]

hey guys,
Im running a lanparty dk 790fx8 board with a phenom 9600 quad proc, 4gb ocz gold mem, nvidia 8800gt 512 video card.

system runs FANTASTIC but i'v decided to go crossfire and need advise on 2 cards to get. i prefer that they be no more than 150 each otherwise i leave it as it is, heck im getting avg 50+ fps with left 4 dead on all high or extrm high settings

advice plz

Would there be any noticeable difference if i added another 8800 gt to the current setup WITHOUT running crossfire AS they are not ati cards?

just get 4870 or geforce 280. Crossfire just adds more heat. It's a marketing gimmick.
