ok guys i decided to buy msi gtx 960 but 4g or 2g ?
Better spend the extra for the 4GB. Especially if you like to play with high A-A, textures, DoF, etc in today's A games.
But be sure your system memory is 8GB or more. Win will carve out more system memory for a frame buffer with a card that has 4GB than with a card that has 2GB of VRAM.
