Should i get the same model of video card i have now or ? What gain and peformance will i get if i run 2 x850xt's on my set up. I do quite of gaming as to BF2 and COD2. Thanks in advance for the replies

You will have to get a crossfire version of the card, or "mastercard". You will see varying performance in different applications/games. Makes sure your motherboard has two pci-e slots, and supports crossfire.
