3dmark2k1 isnt terribly useful as a benchmark these days for graphic card referencing. All but 1 game test is completely CPU limited on modern graphic cards. However there are a few decent tests which scale well with graphic cards. The first important thing I would note is the Advanced Pixel shader test which makes use of pixel shader 1.4. The Geforce 6 series and SLI do exceedingly well in Pixel shader 1.4. It is also interesting to see how 2 6800GTS exceed 10000+ Fillrate in AFR mode. Quite a feat for modern graphic cards and certainly not something I expected last year!
I've just been testing 6600's non bridged and although I get the fillrate improvements like yourself Chris ( though not as much without the bridge ) the nature fps stays the same as a single card .. this is very strange....

In 03 and 05 I get good improvement gains, but 2001 seems stuck for at least nature and dragothic, both of which should scale.

Any ideas ?
