Alright, thanks. Just looked at GPU's at my local computer store (btw I don't live in the U.S. -here, a GTX 780 will cost ~650$), and within my price range there are 2 (non SLI) options:
As mentioned the *R9* ( looking at you Joeteoh99) 280, and GTX 760- they both cost ~330$. Which would be the better choice?

The R9-280 is roughly equivalent to a GTX 670, so you will not get much of a performance boost. You're better off getting an R9-280X or GTX 770.Will SLI GTX 660s have better (or equal) performance to/than the R9 280X or the GTX 770?
660 SLI will perform better I would say.

The R9-285 is basically a slimmer version of the R9-280. It has a lower bus rating (256-bit) and fewer stream processors, but a lower TDP. Either get another GTX 660 for SLI or a GTX 770 or R9-280X.So performance-wise SLI 660 >= GTX 770 >= R9 280X > R9 280 >= R9 285?
More like GTX 770>R9 280X>GTX 660 SLI>R9 280>R9 285.
All are really close in terms of performance.

Yes,it's an excellent option.But if there's a little bit of difference between the GTX 660 SLI and R9 280,while the GTX 660 is $40 cheaper,why not get another 660 and a better PSU,like Antec HCG 620M,Seasonic S12II Bronze 620W or XFX Core 650W?
Because the PSU costs 100$, and if the SLI 660s are around the same performance, slightly less reliable and more expensive I'd prefer the 280.
Also, a friend of mine might be getting a new PC, and SLI 660s are fine with him- I offered him to buy my card for cheap, that way we both win ( my expenses are lower, he gets one half of an SLI setup.

I think the 280 is a good option- especially for its price. Just two questions:
1)If I sell the 660 and buy a 280 my expenses will be just 130$. Is the performance difference worth the money?
2)The exact model of the 280 I'm looking at is: Sapphire Radeon R9 280 DUAL-X BOOST OC. What is the OC potential, and what kind of performance increase does it give?

It's the best possible R9 280 you could've chosen.
Alright, I have checked prices: 280X costs ~415$, the 285 costs ~360$ and the 280 costs ~315$. Considering these prices, which would be the best choice? I might be able to stretch to the 280X, but then I should upgrade my PSU which will add another 100$ to the price.

Listen to me,mate.
The 280X is the best choice,of course.
But you can get the R9 280,save $100 and OC it. That would be a lot better choice.
You just need to raise the clock speed by 100 MHz and you will reach the 280X clock speed.
Tier 1,Tier 2 Class A and Class B PSUs are recommended:

This is how much watts you need for any GPU:

One more time,get the 280,OC it and save $100 that way.
What mobo do you have?

Sorry if I'm infuriating, or asking too many questions- I just want to be absolutely sure of my course of action.
My mobo is a Gigabyte H77-DS3H.
