I would like to ask if 512mb of video card is good enough to run graphical games?

I would like to ask if 512 of video card is good enough to run pc games like gta 4 or assasins creed.|||The amount of video card RAM should not determine how well your games will run. It is the graphics chip itself that will determine how well your games will run. Nvidia 9600GT or NVIDIA 9800GT will suffice or ATI 4850 or ATI 4870 also will suffice along with 512mb of video card RAM. If you worry of whether 512mb is good enough then by all means get a video card with 1GB of video card ram for games with tremendous amounts of textures. Such as Doom3 on Ultra detail.|||GeForce 8800GT is awesome! It runs Crysis on high settings. The best part is that it's only like $150 or something like that.
