gera linkme nukreipei, čia iš tomshardware:
The primary consideration should probably be resolution, because this is a 
hardware limitation for many of us. Typically, 20" or smaller monitors will 
cap out at 1680x1050, so in this case, spending extra on 1GB of graphics RAM 
might be frivolous. Conversely, if your monitor is 21" or larger with a 
1920x1200 native resolution, purchasing a graphics card with 1GB of RAM 
might be a wise investment for only a little extra money.

taigi, jei rezoliucija 1680*1050 - pilnai užtenka 512mb (net ir su 4xAA)
