What is the most memory that I would need in a GPU for high end gaming? I see video cards with 2.5GB+... Is this needed to play games such as BF3? Do you think 2.5+ will be necessary in future games such as Crysis 3?
what monitors, what resolution, what game, what settings, what's your budget, what power supply do you have, what CPU and motherboard?
Single 24", 1080p, BF3, ultra, 500$, Corsair 550, 3570K OC'd to 4.7, ASrock pro 4 z77....windforce 670GTX OC'd to 1300mhz
My vram sits around 900-1.1, just matters the map and situation. This is while driving two monitors, though only the game in one. If you plan on a surround multi monitor setup, then yes, more vram will be needed.
