Current build need upgrade

Another 6850 in crossfire would do the trick.

Inzone has good advice too. Basically, keep everything except either get a new GPU or get a 2nd GPU for CF

We need an idea of budget before we can give any more advice than has been given already.

ty for advice given and my budget wud be around 600-700 more, CF of 6850 can compete with gtx 570?

my games to be precise is WoW, Rift, Cod 3, bf3 and on december Swtor.

If your budget is 600 to 700 then you certianly could get one or two 570's , or get a GTX 580.
