Then it will choose the one with the lowest ram, so you will have 2gb vram

In this case, your SLI or xFire setup will run with the card with the lowest amount of VRAM, in this case, 2GB.

I didn't even think that worked. as far as I thought they had to match if they were to run in Xfire or SLI mode.

running seperately it wouldn't matter, in which case they could be completely different.

If im not incorrect, if you are running SLI with 1x 4GB card and 1x 2GB card the extra vram on the 4gb card will be thrown out the window, however crossfire allows you to mix and match much more :)

it appears this will work for AMD Xfire, but not for Nvidia SLI. if you were running them as independent GPUs for different displays and you weren't gaming across multiple displays connected to different graphics cards, nor expecting them to combine performance, it will work just fine for either as independent graphics cards.

SLI would not work, crossfire would only use 2GB for each card, and if you're talking about one at a time, under 2 GB they would perform the same, and above 2GB the 4GB card would start to pull ahead, the further above 2GB you go, the more difference it will make.
