Question for everyone out there, I've got a pretty decent machine, 4 gigs of ram, 2.8 ghz dual core, 512 MB graphics card, but I run a low resolution on my cheapy monitor, just 1024x768, I can typically run any game on high or ultra right now because of this, if I upgrade to a nice 22 inch LCD that's high def and all of that, how much will my performance drop? What kind of power do you need to run modern games at that kind of resolution?
