Can you explain why you believe it impossible giving similar benchmark comparisons???

Because 3D Mark 06 scores don't work like you assumed here. Doug even linked to an Xtremesystems.org forum post that had the formula the final 3D Mark 06 score is based on:

xtremesystems.org

If you look at that, there's no way a standard-clocked 2900 XT Crossfire system (GPU scores max ~7000/8000) could possibly reach a total score of 23768 as Theo claimed.

If you assume that the cards for the 24k score were clocked at the 830/900 MHZ mark (GPU scores max ~7700/8800) mentioned for the 30k rig later, the CPU score would have to be ~ 55,000 (55k), or roughly 7 times the best overclocked quad-core Kentsfield.

As for the 30k score, again, there is no way to get that with a set of 2900 XTs at 830/900. (GPU scores max ~7700/8800) It's simply impossible.

For 30k to be scored on 3D Mark 06, you need (a) the two GPU scores to average out to way over 10k, something only possible with 2900 XTs clocked to way beyond 1 GHz, and an infinitely fast CPU.

With the CPU at a very generous score, say 6000 @ 3 GHz (Kentsfield 3 GHz = 4600), you'd need GPU test scores to average out to ~14.5k, which is an impossible feat even with the highest clocked 2900 XTs out there.

Short version: Theo's claims don't add up.
