Hello I'm looking to upgrade my rapidly aging Asus 6600GT Extreme with something a little more powerful to allow me to run games well at 1920x1200. I own an Asus A8N-SLi Deluxe so I'd like to stick with an Nvidia card. The things is that I want a graphics card that's quiet! Is there such a thing as one that's powerful *and* quiet? I was looking at the XFX cards as I've heard good things about them but I've just read that they're noisy as hell with their fans often running at 100%. Any other suggestions?
