Help me upgrading my not for gaming pc to a gaming pc!

@ Puiu
with the exception of Far cry, you are looking at a 2% difference, that hardly makes the x8 interface "not very useful". unless the OP is going to build strictly for the purposes of benchmarking competition. and keep in mind that the benches you provided were all done in 2560 x 1600 resolution,max details, and max AA. also, if you look at most of the scaling studies done, the difference in FPS is more likely attributed to the chipset used.

hey ok i know that but jut for having an idea plz post the links og the pc stuff the monitor must be a 24" one, g11 and a good mouse. dont exceed the 1600 dollars plz man only if you can
