3Dmark has lost alot of respect for one main reason.
Can you say 2900Xt's? And many other ATI products, many 3Dmark scores award higher points to certain ATI cards and setups even though in actual real world benchmarks such as the crysis benchmark, many other cards beat the crap out of 3Dmark06 Champs.
For a long time the 3Dmark06 world record was on 2900Xt's (Or pros, I don't remember), but we know very well how many better cards there are.
I say the crysis benchmark more so than 3Dmark06.
But, again, it is all relative to what you use your computer for and if it is for gamming, which game you care most about.
