3870 @ 1200MHz Core w just Dry Ice

[Kinc]

Very nice Peter!

I would estmate that your 3870 clocks is pretty equal to a 2900XT running 1160-1180MHz core with 950-980MHz frame buffer, it might even be just as fast. That GDDR4 speed offers alot of bandwidth wich should be enough to compensate for the 256-bit interface. In my testing on air cooling if you max 3870 and 2900 frame buffer freq with gpu set at 800MHz the perf is pretty equal in 06.
