Aye, but Nvidia cards no longer use an AGP-to PCI-e converter... That was the first wave of Geforce 6's... But Gog has a good point. There's a lot more going on than just the surface numbers. When building the best RENDERING machine, AGP and PCI-e slots mean nothing, at least as far as Bryce itself is concerned. You'r fine, lots of RAM, a great and PROVEN great processor, the only thing I would be concerned about is the price. You're paying nearly double what you should be, which would be fine if you were getting some overpriced rig from a name-brand company like Dell or Alien. They make great machines, I guess, but who would want to pay 800% overhead? Then again, you get what you pay for, right?
