Am thinking of upgrading to the gtx 660 am I currently using the 7790 which I get decent frames with but would like something a little bit more powerful. Other options am looking at are the 7870. So my question; is there significant difference in terms of performance between the7790 and the 660/7870 or should I be looking at something higher up? And does a 3Gb card perform better than a 2GB?

My system
Core i5 4570
8GB RAM

a gtx660 would be a modest upgrade. a 7870 would be a slight bit faster than the 660 for about the same price. at the moment no games max out 2gb cards at 1080p. a 3gb card may come in handy in future titles though. I would aim for a 270x/7950/gtx760 or 7970/280x for a more noticeable jump in performance if it fits in your budget.

If you have the option on your motherboard you could crossfire two 7790's, which would save you money and give you more power than the 7870/660 with games that have crossfire support. The 7870 and 660 are two steps up, some would consider it a worthwhile upgrade, others don't. I personally would go with something higher like a Radeon 7950 or R9 280x as a single card solution.

the 660 will be around 20%-30% faster then the 7790... the 7870 will be about 35%-45% faster. (the aforementioned r9-270x will be at the top end of that stretch) and the 7870xt will be about 55%-60% faster.

You mean that the HD7790 is that much slower than those cards, If the 7870XT is 100% and the 7790 is 50% then the 7870XT is double the performance or 100% faster.

nope. the 7790 is about 66% of the speed of the 7870xt. in xfire a 7790 will come in a tiny bit faster then a 280x/7970...

I have my own love hate with tech powerup i won't get into... just know that a 2x 7770 in xfire will come in around a 7870xt, while 2x 7790 in xfire should come in around a 7970 (vanilla) or a little slower (but faster then the 7950 by a little bit); while 2x 7850 in xfire will come in somewhere between a 7970 and a r9-290 (a little closer to the 7970 then the r9-290)

the problem there is xfire is unpredictable, can deliver worse performance than a single card, frame-times and microstutter can become apparent, and lower end cards are often only fitted with 1gb vram. 2 cards never give the same smoothness/predictability of gameplay compared to an equivelant single card.

Well if you looked in the link you will see it is pretty much equal with HD7950 until you hit 2560 x 1600 res the 7790CF gets destroyed and dragging the average down.
