guys i can sell my current dual 5870's for 500 $ and i can buy GTX 580 and 3D monitor but im confused should i do that or just buy 2560 X 1600 monitor
I'd definitely go with the 2560 x 1600 monitor. It's the ultimate! 3D is great but I'd get that in TV form and hook it up to your computer or a PS3 maybe.
I've had dual monitor configurations and even though there was technically more real estate, pixel-wise, it didn't come close to how well my 30" monitor performs.
