ive been running the benchmark this whole time and it hasnt froze yet. Weird. the highest ive seen is about 86. also there shouldnt be a compatibility issue with the Radeon and a P5N-E SLI motherboard right? i think it has Nvidia chipset drivers off the disc but does that have any effect on why the games are freezing?
Are all the games running in DX10? They're still working the bugs out of it. Try running it in DX9 and see what happenes.
