Question about VRAM and SLI My current set up is an i5 2500k @ 4.5ghz stable/8gb/560ti Twin Frozr II 1gb.

I would like to attempt to max out BF3 when it comes out by adding another card, however it seems that there is buzz going around that the game will utilize more than 1GB of VRAM. 

When in SLI, two 1GB cards will only be recognized as 1GB of VRAM.

Unfortunately, I purchased a 1GB without much research and had a cushion of many commenters on buildapc saying that 2GB isn't necessary.

Should I scrap the card for a 2GB one or will I be fine?


What my question is and google can't solve, but how does my future lack or VRAM affect the performance of the game?
