josherrr :
i think i should rephase my question...
my question is will any game out there push my system as hard as furmark pushes it?
All the latest 3D games out there can push your system as hard as furmark (Crysis, Cryostasis, etc) How? Just set the graphics to the highest resoltuion your monitors allows, then, set the textures, details, shadows, AA/AF to the highest levels, and watch your framerates go below 10 frames per second as your system strugles to give it everything its got.
Furmark is good at finding your GPU heat threshold when it starts to say "this temp is too hot for me so I'll stop working properly and give out artifacts".
For testing, each of the cards I've used (8800 GTS, 9800 GT, GTS 250) to play Crysis all started to give artifacts at around 81 - 85 C but it wasn't a problem for gaming because it never got that hot because I'd set the GPU fan to 80% before gaming.
