Thats near my dream(affordable) system ya have there Incarnadine. Would love to watch that Opteron render in B6.

I have XP Pro x64 OS, and ya might want to pick that OS up as soon as you(all) can. Vista will be full of bloat and slowware. There is alot less crashing in all my 3d apps including Bryce(I still have 5.5c)because it handles lots of ram and BIG scenes really well. Also x64 is multi CPU aware right out the box. It would compliment that system.

The benchtesting with duals and B6 are cutting times in half for most people. Now if I could just get some green(B6 is also green, get it  )to buy a similar system.
