Thanks very much for finally giving us some data to hang our hats on answering questions about WoW hardware and performance. I've long known that SLI hurt, not helped, FPS in EQ and EQ2, but got laughed at when suggesting WoW players not depend on SLI/xfire. I couldn't prove it because I had abandoned SLI by then. Vindication feels good.
I wonder if you have any info on another general statement that may not apply to WoW . . . that more than 4GB of memory doesn't help games. The three WoW PCs that I run have too many differences to prove the point, but I get inexplicable relative frame rates on an 8GB 64-bit Windows 7 machine with a 5750 compared to a 4GB 32-bit WinXP machine with a 5870. While this could be due to different Intel cpus, mobos, chipsets, etc, I keep thinking getting the OS, Ventrilo, various Logitech and Zboard drivers, Norton, etc out of WoW's address space allows WoW to run as freely as possible. Any thoughts?
