My old 8800 is getting way too noisy. I have a 2600 I can use for osx(which I seldom use ) so I decided I have no need for a mac compatible card but one would be nice. Looking for suggestions which one to buy. Usually work with 2d-applications, but sometimes play some games like SC2, D3, DA, AC etc in 2560x1600. Want a quiet card and would prefer a low consumption card. Where is the sweetspot right now? This one for ~$150? PowerColor Radeon HD5750 SCS3 HDMI DisplayPort Dual-DVI 1GB or go for the 5850?
