OK. I'll stick with single monitor for now. Right now I have a 1920x1200 but may move up to 2560x1440 sometime.
Games I plan to try out: iRacing, Netkar Pro, rFactor, Forza, Simbin titles, DIRT titles.
Using Dirt 3 (as it's widely benchmarked): At 1920x1200, an HD 7770 or HD7850 would work ok. If you plan to move up in resolution, then consider the HD 7850 as a minimum and the HD 7870 or GTX 670 as good. Too bad Nvidia is dawdling around with the 660 family release - it'd provide some competition at 1920x1200.
Given the current power of IGP, is it possible to use onboard graphics with an i3-2100 and basically shut down the video card completely until gaming? I.e., is it possible to have the video card fans turn off when lightly using the system for browsing etc...?
Haven't seen anything that turns the cards completely off...I was hoping that Virtu on the IVB boards would enable AMD's Zero Core state when the dGPU isn't used..but so far, no joy from the www. That said, there are some fairly quiet at idle cards out there. Here's a 7850 review thread
I've been compiling. HT4U tends to have the quietest test setup to compare cards (other than here
). There's a GTX 670 thread here
