XFX has a great overclocking performance (says in some of the reviews) but Sapphire has the bigger memory. Right now I use single display with resolution of 1920x1200 but I might buy a second display in the future and most probably, I will do overclocking for some hardcore games. Silence of the card is important for me.
Here are some more information about what I want.
APPROXIMATE PURCHASE DATE: 2 weeks
USAGE FROM MOST TO LEAST IMPORTANT: Gaming [hardcore games like Crysis, home theater/watching movies
If you plan on using eyefinity (3 monitors) I would get the 2GB version, if not... it doesn't really matter.
Even if you have 2 monitors and you play in one while you watch a movie or surf the internet in the other the 1GB will hold just fine for that, if you plan on adding a 3rd monitor and play on them then the 2GB will be better for that.
Yeah I don't really see that being possible Imagine playing a first person shooter and the cross hair would be between the two bezels of the screens! Technically it would probably work, just in practice you'd be better off using one screen, and just using the second for browsing, movies etc.
