Download and run SIW (google it). Go to the sensors module on the left.
Fire up crysis (keep SIW running). Play for a bit (15 - 30 mins)
Quit crysis and check the maximum temps. Post a screenshot if you can.
Edit: Oh and patch crysis. It solves a lot of issues.
Sorry, I returned the cards before I read your post. However, the last time I checked temperature when FPS dropped down, the ATI application said the temperature was over 90 degC.
Patching it will enable better CF results and solves some artifact problems. So how's the 285? How's it running with Crysis?
lol. so now crysis works?
On 1920x1200, AA=0, and Very High Quality.
fps hovered between 23 and 37
On 1920x1200, AA=8, and Very High Quality
fps was between 9 and 15
Do values for 8xAA sound about right?
I couldn't find any benchmarks for that.
