Businesses are supposed to cater to the people that pay them, and anyone willing to buy a Dell or HP performance/enthusiast PC would look and say "OOOH! 4 core processor and 4 GPUs!!! MOM!!! BUY ME IT!!!"

From something I read a while ago, the Crossfire architecture supposedly supports a linking of up to 32 cores... At minimum they should support their new baby and everyone willing to buy 2 of these cards.

This card WILL support 2 of these in crossfire to have quadfire when the X-fire drivers are ready. That's what they have been advertising for months already, didn't you notice? X-fire = up to 4 GPU's. In Vista / DX10.1, that is.

I flashed the card with bios of different wendor that didn't show 860MHz limit and the limit is gone, but it is significant pefromance drop:

3DMark06 score at @860/955
original bios (with 860MHz limit) = 20080
upgraded bios (without the limit) = 19500

How to look for an 860MHz limit in BIOS?

Wait for W1zzard and I's BIOS Editor. That will be a while.

Search for 860 in hex?

Did you notice that ID0 was 42Kb and ID1 was 62Kb for the original BIOS when saved?

yes, ID0 is slave card, so that's why

might have to do with memory timings, did you check them?

Yeah likely that your first BIOS was tweaked for better performance..

If 860 is specified directly then it should be this string ... F0 4F 01

Or for 861 ... 54 50 01
