Current system specs below Opteron 2.8Ghz (can do 2.9 but throttling back to put that out the equation) Geforce 7800Gt (stock) 2X 512mb of Ram diffrence brands running at 217mhz Dfi Ultra D mobo Hiper 580W Type R The problem i am having is in games like need for speed most wanted the frame rate is fine say 50fps and then it will pause for a 1/4 of a second and then play and then pause it does this every 40 seconds or so which i think could be due to it having to draw new textures. This also happens in quake 4.. games runs fine when threes lots of action but at some strange points it will do a similar pausing. Do you think the low memory bandwidth could be the problem or possibly a psu issue? It really is starting to bug me as for the game need for speed most wanted it doesn’t matter what i do it still does the jumping every 1/4 second. Even after lowing the graphics settings considerable .
