indeed

The HD5870 MIGHT reduce its clocks though.

 

[obsidian86]

ati is not nvidia it wont reduce the clocks

 

[paperfox]

I thought that ATI cards downclocked and Nvidia's did not, though they used to with pre 156.something drivers?

 

[pnico]

has anyone seen any preliminary benchmarks with fermi vs the5970?

 

[shadow187]

Fermi is better than HD5870 with Tessellation due to GPGPU capabilities. HD5870 is better in every other game, I think. HD5970 will dominate its ass.*

*IIRC.

thats why its possible to crossfire similar ati cards and not the exact cards like in sli

Yeah, started with 3-Series.
3850/3870/3870X2 CF's were possible, expanded to include all of 1 family in the 4-series.
4830/4850/4870/4890, 4650/4670, etc.
