Is it worth the extra money for exrta GPU memory?

[Sirwalrus]

I'm planning on purchasing a GTX 680. I'm leaning towards the 2GB version, because my monitor will only support 1080p, but I'm planning on eventually running SLI 680's at possibly 1600p if I get the monitor, so Will it be worth it now to spend the extra for the 4GB? I know more GPU memory is mainly helpful at high res, but I'm not sure I want to spend more money right now.
I'll be buying the reference MSI version of the 680 because I preffer the way it exausts air over the Asus and Galaxy models.

So, would you suggest spending extra money now to have what I need in the future? Also, anyone here have a reference 680? What kind of temps and noise do you get under load? Thanks.

the best bang for the buck from the research Ive done is to run two GTX 660ti's in SLI. It gets roughly the same performance as two gtx 670's and it outperforms the new ($1000+) GTX TITAN card.

-if you dont want to run SLI just yet... buy 1 gtx 660ti and when you feel the need for an upgrade buy a second. As of right now the 660ti can run any game on the market on max settings with great fps! I run crysis 3 on all high 30-50 fps with 1 card.

you need a 700+ wat PSU to power 2 of them though.

Most benchmarks I've seen show quite a performance increase from GTX 670 and 660 Ti.

Now the 670 is near 680 in performance, but the 660 Ti has a reasonable gap. Although if you where suggesting the 3GB model since I'm wanting memory for future proofing, it's something I considered, but I'm looking for a little higher end.

EDIT - I'll be running a Corsair AX850 silent pro, it's gold certified, so I souldn't need to worry about the PSU.
