I'm trying to play these games and future games that may come out. (Sims 3, Mirror's Edge, Batman Arkham Asylum, Prince of Persia, Burnout Paradise, Fuel) A few of these games need a minimum of 256 MB Video Memory but all of the 256 MB cards on newegg have a 64 bit interface. Will that allow me to play these games or should I spend a little more money and get a 512 MB with a 128 bit card or maybe even a 256 bit? Also should I be looking at ATI or NVIDIA?
