I am currently playing WoW on a latitude d830 with a nvidia quadro nvs 140m gfx card. i have been told that gfx cards is absolutely abysmal for gameplay and it is showing up in my fps in wow (usually around 40 fps while playing at like 700x600 resolution). so what would be a good idea for a desktop or laptop that would be good to run wow smoothly within a 500 dollar price range?
