I was wondering if it is worth upgrading from an HD4850 512MB. After reading some posts on here about gaming on higher res' and needing a 1GB card as standard. I upgraded from a 19" monitor (1280x1024) to a 24" 1920x1200, and was wondering if it's time to update the graphics card too? If so what should I upgrade too, and a little paranoid that my PSU won't be able to handle it. Specs in sig.
PSU currently : Hiper HPU-4M580 Type M CrossFire Certified 580W ATX2.2 PSU - Black
