@ZeeWolf (and others),
Well, I am determined to enjoy and the the most performance as possible today (without going to an SLI/CrossFire setup as they have their own issues), so I am selling my current ATI 5870 and replacing it with an nVidia GTX 580, the fastest single-GPU video card money can buy. I'm also going from 4GB RAM to 12GB RAM, thought I don't think that will directly impact performance.
As soon as I get everything installed/configured/etc., I'll fire it up and let you know what (if any) difference this setup makes.
My hard-earned $$$ for research I guess!
