I play World of Warcraft on a Toshiba Satellite p35 S609 notebook. It comes stock with 512mb of memory, and an ATI Mobility Radeon 9000 IGP. I have increased the memory to 1gb, But I plan on increasing it to like 1 and 1/2 gb soon to increase my gaming performance. Does my video card need upgraded? And if so... what video cards are compatible with my notebook, I can't seem to figure this one out. Any help will be highly appreciated.
