If you are talking about great performance or poor performance with high-end equipment, be sure to include the resolution you are playing at. Saying you play everything at max with zero stutters doesn't mean much if you're using a 15" CRT @ 1024x768. Also saying the game runs like crap on your i7 and 3GB card is a similar situation if you're trying to span it across 3 25" monitors, each at some crazy-high resolution.
