I have a 640$ gaming computer. i can run source on med/high 60+ frames and AAx8 and cod4 low graphics 60+ frames AAx8. my monitor is runing at 75 refresh rate. and my games still skip. my cousin who has a 5 yr old computer runs cs 1.6 better than i do. and his monitor runs at 75 refresh rate. his computer is worth like 5$ and no i do not get frame drops when my games are skipping. my 1.6 game for example will run 100fps flat and still skip. its not BAD but it iratates the crap out of me i buy a machine that shouldnt do this.
