I have just built a new i7 machine cranked to 4.0 with a 560ti vid card and my quake 3 timedemos at 986fps. My old system with a Q9650 cranked to 3.3 with a GTX 275 would reach about the same. Is there some limit in quake 3 that keeps you from getting over 1000fps? Something other than cpu/gpu like something sound related? I still play at 125, but am just curious if it can be done.
