Hello,

I think I know the answer already but I thought I'd ask just to be sure. I have a 560ti (fermi) and I'm pretty much hit the wall with what I can do with it. I saw a deal for a GTX 670 Here and am getting it. I know if you SLI two cards with different amounts of VRAM that it will use the lesser amount. Since they have the same amount, is it worth it to SLI them? Or is the 670 alone the way to go.

Thanks.
