Hello, I have a gaming computer that is currently running a single GTX 760, I am on a very tight upgrade budget and would like to know if it is worth buying a second 760 and putting it in SLI. Also, do all games support SLI, if not which ones don't? I am also worried because I have heard a lot of horror stories due to SLI (my PSU is 750W). So is it worth it and what games support it?

Not all games support SLI (usually ported games, i heard people had troubles with Metal Gear: Rising Revengeance while doing SLI or Crossfire) you PSU is more than enough, and the benefits of SLI i don't have them very clear but they're good and increase performance substantially, without the need of throwing your GPU to the thrash bin and buy another, if you tell me what your motherboard is maybe i'll tell you if it will not explode when you plug in a second card :D

Not all games support SLI in the first place.
SLI gives ~60-80% better performance in the games that do, those that dont get no benefit.
A quality 750w is enough.
Unless you have the 4GB card dont bother either way, as 2GB cards are limited in SLI.
Depending on resolution and needs either keep the one, or upgrade to a single better card.

My motherboard is an ASrock extreme3 and I have 2 GB 760, can I know why this is bad? I only intend to game at 1080p, and how many games support SLI?

Most all newer games support SLI there are a few weird ones that don't though. Sometimes you do need to wait for driver updates before you will get good performance SLI. Most of the games that don't support SLI are old enough that a single card can max them out. 2Gb will work just fine with SLI you just may lose a couple AA settings etc though.

When you SLI you are limited to the Vram of a single card, they dont add. So you would be limited to 2GB, and if you hit the Vram limit you would have severe stuttering. You wont get as much out of a 2GB card as you would from 4GB.

A single 760 should be enough for 1080p.

Should be good enough, If it wasn't sell/return it and buy a 770. Don't sli unless the games you want to play is known to support sli well and you have enough vram (for both cards on one of the cards)
