O/C 6800le unlocked what is reasonable?

[BrokenArrow]

I have a Chaintech 6800le unlocked to 16/5 and currently o/c'ed to 370/770 (up from 300/700 stock). I have installed a Zalman VF700 AlCu to replace the stock cooler. Is this a reasonable O/C for this card? I'm getting just over 10k in 3d03 and just (a hair) over 4k in 3d05. I know it has the 2.2ns memory chips. Anyone think it should do more? Any (useful) opinions welcome. Thanks.

I saw one with an unlocked BFG 6800nu that got up to 800+ on the memory, but that seemed pretty high. I'm buying an unlocked evga 6800nu with stock cooler that hits a similar OC. I plan on putting some kind of aftermarket cooler on it and seeing how high i can go
