Unfortunately that is not 100% stable with the stock cooler, it is OK in ATItool until the temperature reaches about 58 to 60 degrees then it occasionally artifacts. I have not tried Crysis as I only have that in Vista, my XP hard disk that I do overclocking with ONLY has XP and the necessary overclocking/benchmarking tools.

So far 720/1728/2050 (approx) is completely game stable but for day-to-day gaming I run at bone stock 600/1500/1800 as that is fast enough for what I play generally. I am sure I could go a bit further than that stable but I'd much rather get the benchmarking results then go back and play games than find the max 100% stable speed that I will never use.
