Hey fellas, can someone tell me if my xfx radeon 7770 can max out and consistantly run (without the stutter and lag effect) for COD:ghost. I feel my rig is under-nurished with low to mid-range components; I'm in the market to upgrade in a big way: just tell me how far i have to go to build an absolute monster gaming rig just to play (Ghost).Isus M4a785x4 core,560W psu,1TB HDD 7200rpm phenom II 3.2ghz,6Gb ddr3 ram,xfx7770oc GPU and win7Ultimate on a 32inch.hdmi/dvi tv.
