That's cleared it up for the OP
Yes for the extra GPU power and the value.
No for the small vram.

So there you have it, two GTX 560 Ti cards setup in SLI will still cost you say 480 EUR, and that's a truckload of money. In that same price segment you can also pickup a more convenient GTX 580. With SLI you might run into some sort of small driver issue at one point in time, also compared to the GTX 580 you will consume more power. The flipside of the coin however is that the performance beats any 'single GPU' graphics card tested to date.
Whatever you preference might be, either way we doubt you'll regret the choice you will make as this certainly has been a pleasant experience from A to Z. Definitely recommended.
Don't get dragged into the VRAM debate with hamony, he'll drive you nuts.
Personally.. I'd go with the fastest single card you can afford, as long as the SLI isn't significantlly better than the single card.
At least you should let the OP know that with 1GB vram per GPU he wouldn't be able to max out games like Shogun 2, GTA4 etc without hacking the games, if not going to mention the tale of "lag spikes". Otherwise the OP might eventually get disappointed if not prepared for that.
..... if not going to mention the tale of "lag spikes". .....
Either you're wrong or just very bad at putting forward your arguement.


Based on the average frame rates SLI'd GTX 560Ti's are a fair bit better than a GTX 580 and for the OP they would be a lot cheaper than a GTX 580 as well.
Or the majority didn't receive higher education, especially with a degree in Computer Science in a top UK university.
You are right, writing an article that is easy for the majority to understand and accept is a lot more difficult than writing an academic paper. I'm not doing well in either
 <-- but I digress.. save it for the other thread.

Which part of the degree course covered VRAM with CrossFired or SLI'd graphics cards?
 If you really wish to study more in vram then taking a course of "Computer Graphics" or even "CUDA programming" would be helpful.

 They obviously need to improve quality control, right?

Perhaps he could write a paper on it, or study it unbiased for a mastersI've got some left over credits from UCE if he wants them lol.

Many courses could teach you the basic theory, such like Computer Architecture, Operating Systems, Database Management Systems, etc. They all cover the basic concept of "thrashing", "pin page", "swapping" etc. Also, some basic knowledge about Statistics would be helpful. Though I have no idea about the average level of the majority.If you really wish to study more in vram then taking a course of "Computer Graphics" or even "CUDA programming" would be helpful.
 At this point in time after reading that, I'm not sure you've actually been to uni *, given that a lot of computer courses don't actually deal with hardware at all, some not even binary (good grief!). Not that it matters, if your argument actually stood up and you presented it a way that wasn't so "I'm right", you'd be ok.
