What he said. We prefer AMD Athlon 64s over Intel for performance, price/performance, and heat. Socket 939 (Athlon 64 and X2 dual core compatible) motherboards with PCI-express x16 slots are very affordable right now. Athlon64s have the memory controller integrated right into the CPU, so they all take DDR400 (PC3200) RAM with no ECC. This should be cheaper than the registered ECC RAM required by the server board you listed. The on-board ATI Rage XL graphics with 8 MB dedicated RAM will not be up to stereo. We are building a couple 'stereo' graphical workstations right now and will be going with the Quadro FX1400 cards, which fit in a PCI-express x16 slot. Here's the Stereographics product compatibility page: http://www.stereographics.com/support/boards/brd-chrt.htm Cheers, -- ======================================================================= I've gained no wisdom, no insight, no mellowing.
