Currently with just 1 card overclocked - I can play everything I throw at it, in Ultra with no major issues.
( except the 64 player servers when everyone is crowded defending a flag like in metro.)

I am assuming I would get a boost in performance.

If I had the money I wouldn't even bother with doing this.
My budget would be $200 if I sold my own card.... I don't see much in that price range that would be a huge performance boost.

1gb gpu = 1gb of vram.

Two 1gb gpus in sli = 1gb of vram

Three 1gb gpus in sli = 1gb of vram

Same goes for Crossfire. Just the way it is and two GTX 560 Ti 1gb cards in sli will have issues with it's 1gb total vram usable amount.

2gb is the minimum this day and age with graphics cards imo.

Because, iirc, when you run games, the ENTIRE data set is mirrored into the vram of each card, regardless of whether portions of it are used for rendering a frame or not.

With SLI/Crossfire, you gain more horsepower to process more pixels faster, not a bigger engine that can hold more data.

Exactly.
To be honest, my advice would be to hang onto your money for now, and save up a bit until you can afford to buy something in the range of a 760 or thereabouts.

I wouldn't do it. At my resolution I was hitting major vram bottlenecks with AA with 2GB vram in some games.
Now that I stepped up to the the 7970 everything is much, much better. Of course I game at 2560x1440.

Thanks guys... I won't get the additional card, and just save up for an upgrade when some game fails horribly in a few months.

Honestly, what does this have to do with this thread? You are talking about a $400 3gig card.
