And I have posted the spreadsheets (and benchmark file) on my se= rver at

http://www.teddygage.com/AEBENCHCS6/

What I would love to add are any results with the newer qu= adros (5000 / 6000) or any tesla card.

Furthermore I'd be interested to hear any thoughts from = 3D users about their experiences using an AMD 7950 vs nvidia consumer card = for viewport 3D (using zbrush / maya / or C4D especially)

The amount of C4D work I've been doing has only increased in the l= ast year and I can imagine when CS7 comes out that's only going to incr= ease. viewport accuracy is going to be of a larger concern and nvidia is us= ing a poor strategy to differentiate the quadros by gimping compute perform= ance in the 6xx consumer cards.

Would also love to hear any thoughts on these results, I'= ;ll refrain from saying what I think until people get a chance to check it = out.
