Hey everyone, so first off I have used both a EVGA 275 GTX and a ATI Radeon HD 4890 (currently installed).. So I can watch movies, and do jsut about everything perfectly fine until I start playing any FPS games, such as CoDMW:2 .. It seems like its 3-4 frames per second and I know this isnt right.. I switched out the EVGA to the Radeon to see if it was the gfx card.. but they both did the same awful FPS.. so Im thinking its the MOBO .. I have a EVGA x58 SLI mobo with a core i7 2.66 GHz processor.. I have even changed the PCIe lanes to see if the lane was damaged but nope, anything I do the fps suck.. Please let me know how you think I can fix this problem and if it indeed is the MOBO..
