GTX560 (nonTI) SLI vs Single GTX 770

[rayf01]

I currently have two GTX 560 (non-TI) in SLI, 1 GB OC Gigabyte cards. I'd like to recoup a bit of money out of them before they are paper weights and I feel they will be at that point with the 800s come out.

My question is, would upgrading to a single 770 be of any performance gain worth spending the money? And would a 2GB version be good enough or would you have to spring for the 4GB?

A single GTX 660 Ti would give you same or slightly higher performance than two GTX 560 Ti.
Since you have GTX 560 x 2, they would be around or weaker than GTX 660 Ti.

Now since GTX 760 is stronger than 660 Ti and since GTX 770 is much stronger than GTX 760, it naturally becomes a stronger card.

There would be some decent performance gains overall. I suggest you to upgrade to 770 now and you would get 60+ FPS on every game out there except Crysis 3 provided you have a good enough CPU too.

Based on these two:
560 benchmarks
560Ti sli vs 770
And the fact that a 770 is just a highly overclocked 680, I'd say you would get quite a performance gain.

I have a GTX 560Ti and I plan on upgrading it to a GTX 770 too.
And like you, I'm heavily doubting between the 2GB and 4GB model.
For now the 2GB model will suffice for 1080p gaming.
But I fear that it wont be enough in a year or two, when game developers will grow VRAM hungry due to the upcoming consoles.

I'll probably stick with a 2GB model, and will see what that GTX 800 series brings. If those are a substantial upgrade compared to the 700 series, I might sell the 770 then.

i know for a fact that 2 gtx 650 ti boost outperform a single gtx 680
gtx 560 is powerful but 2 can't beat a Gtx770, however the difference may not be big in some cases (namely crysis 3)
i recommend you sell the gtx 560 for 110$ each and get yourself a gtx770 (2gb is good if you have a single monitor)
