Recently inherited an 8-core Mac Pro which is going to be my new rig for digital concepts in PS, Painter, Zbrush and Mudbox. 14GB and 2.5TB of space. I have a 4870 that i bought for it a few days ago that performs adequately and consistently, but I feel like the GTX would have longer legs into the future. I'm concerned about the poor experiences pros seem to be having with it tho and dont want to trade up if I'm going to buy a $500 lemon (as I understand its a combination of poor driver/os support and inefficient powerstates). Most of the benches on the net seem to be under 10.5.8 with original drivers. Has anybody checked for changes under 10.6 or with newer drivers? Anybody with an ADC account try out the new drivers included the latest 10.6.1 seed?
