How many users have SLI/Crossfire?

I read somewhere about 2 GB of DDR3 on a GT 430.

Will that do it? Almost certainly, it will not. The amount of RAM is maybe right, but the card is too weak, and the sort of RAM is too slow.

It's not only the right card, but also the right sort of RAM as well as enough RAM that is needed.

It's was even silly to put more VRAM on GTX460 and GTX560, they always put faster memory on 1gb card and it preformed better. Maybe even GTX 660 I'm not sure.
If you run out of frame buffer it'll swap textures with the hard drive, a spinning disk will have a slight stutter. You shouldnt notice much with SSD.

Ehm, that is, why I said that you need to think first and not buy sli just to upgrade an insufficient system. And there are simply people out there thinking that to buy an additional card and run sli will free them from performance problems. I call them bf3 kiddies, who do not know what they do. And in my whole experiences, the percentage of dumb users is about 80% and still rising. It is a shame, how often I am confronted with these sort of people. And I am the one, they talk to.

I just always say the same:You didn't hear my advice and now have problems. Stick with it, because there is no solution in solving it except buying again a new card. I cannot help you and do not want to repeat again. You took an advice of a bf3 kid and now you have the problem. Go away and aak him, how to solve, but not me.

Just said, that a youtube comment counts more than the opinions of an honestly explaining gaming friend. I cannot help dumb and ignorant people, who will not listen.

Again: sli = in most cases not to upgrade, only to enhance. If your card is shit and cannot run the game, it would not help to buy a second one.
