Hey guys, I just installed and ran WoW on my Athlon 850 MHz system (GeForce 4 Ti 4600 GPU w/128 Mb vRAM, and 512 Mb of system RAM), in the same 4 vs. 4 dogfight I mentioned above, with 2X anti-alaising turned on, and triple buffering enabled, while running 1024 X 768 screen res the game again performs smooth as silk!

Note this system is below the minimum requirements for the CPU as specified by the manual...........I'm pleased with this result!
