This question is actually of importance to me as well. I'm currently running XP but I own a legit copy of Vista that I simply never use because it seems that in single box play, with my settings cranked at max my framerate is considerably lower than when I run in XP. Does this change for some reason when running multiple clients at lower resolutions, which I would be for playing multiple accounts simultaniously? I plan on playing two accounts at first, three at the very most.

My system specs are as follows:
EVGA 132-CK-NF78-A1 LGA 775 NVIDIA nForce 780i SLI ATX Intel Motherboard
Intel Core 2 Quad Q9450 Yorkfield 2.66GHz 12MB L2 Cache LGA 775 95W Quad-Core Processor
EVGA 768-P2-N831-AR GeForce 8800 GTX 768MB 384-bit GDDR3 PCI Express x16 HDCP Ready SLI Supported Video Card
Crucial Ballistix 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory

Currently I've been having a few video issues in XP with any 3D accelerated games but EVGA seems really cool in helping me get that problem solved. I also have no problems dropping another 2GB of memory in provided it would vastly improve my performance, however since I've previously been only running XP and it doesn't truly support much more than 2GB of RAM I didn't feel it necessary.


Thanks for your input!
