I'm talking about 1080p too. Turns out Bioshock Inifinte needs about 1.3GB for 1080p on full detail; It's a pretty game, but it's hardly a modern engine (UnrealEngine) - Newer engines with fancier effects like Crysis3 or BF3 can bring 1GB cards to their knees.
As others have said, just turn down the details and/or resolution and things will be fine; but it's hardly an upgrade if you have to keep reducing details for decent performance.

But if you have to turn down texture quality and other graphics settings, it's not really an upgrade - especially since the 2GB card that costs less than two 1GB cards handles those higher settings much better.

As I said above, no one is buying a 1GB card, that we wouldn't do. The thing is we are trying to achieve similar levels of performance (2x 560TI in SLI in one PC and a 760 in the other, for instance) without spending to much money. I was only asking what experience with SLI you guys have

On paper it looked really nice - 1736 MB RAM, awesome fillrate, very fast - but on closer examination there were a number of problems. In order for both cards to work on any given frame, contents of memory between both cards must match, which means that you're effectively knocked down to 896 MB RAM. Synchronizing between the two cards also incurred some overhead, and in some demanding scenarios I could notice a very small amount of microstutter between them. Finally - and this is not to be underestimated - it ran HOT, at something like a 265 watt TDP, and it was LOUD. I'd expect a physical two card setup to run even hotter due to the lack of shared resources, and if you allow for sufficient space between cards it will take up a lot of expansion slots in your system.
I sold it and used part of the proceeds to grab a GTX 660, which is perceptibly faster and uses about half as much power (and a smaller fraction of the noise). Grab a 760 for yourself, then encourage your friend to save some cash, sell the 560, and buy at least a 660 for himself. A 560 Ti SLI solution is probably not going to age well if you're trying to think about the future.

I originally had a single nVidia GTX 670 and added another GTX 670 of the same brand/model. The heat in my room and case both increased noticeably. My case, a Corsair 550D, has only average airflow, therefore noise became a big issue (both video card blowers would ramp to high-speed when playing games due to their mutual proximity). Despite a clean install of Windows and nVidia drivers, my performance in Crysis 2 was about 25% lower than identical benchmarks, with apparent stutter even at 60+ FPS. I had to disable SLI completely in Bioshock 2 because the game kept freezing. The heat, noise, and other issues just were not worth any performance boost. As a result, I'm looking to sell both GTX 670s and replace them with a single GTX 780. Although this will be a performance downgrade, I view it as a net gain.
