I am not satisfied with single HD7970 so i was considering either buying a second one to put into crossfire or swapping my current card for GTx 690.
Wich would be wiser option, not all games support Crossfire well after all.

What resolution? If multi monitor the GTX 690 won't be as good as the 7970 I'd believe since it's technically 2x2GB cards, i.e it has 2 GB of VRAM in the end.
The GTX 690 is in itself a multi GPU card, IDK if games which don't support multi cards will actually read both cards?

GTX690 will act like a SLI setup. if a certain game has a problem with SLI, so will the GTX690.

Grab a cheap 7970.
Cheaper, less hassle (dont have to sell 7970 atm), and call it a day. What res are you playing a 7970 should be fine in 1080p/1440p on one monitor.

Get a second 7970. They scale better (crissfirex scales better than sli)., have an extra GB of VRAM, and outpreforn a 690 at stock and destroy it if overclocked.

though in my experience with the past, micro-stuttering is worse on AMD cards. perhaps it is not the case nowadays.

My current resolution is 1920x1080. I plan on getting a new 120Hz monitor(with same resolution) when i buy the second GPU too, currently i have a few years old 60Hz BenQ monitor.

Since the catalyst 13.2 drivers came out, the frame latency (micro stuttering) issue has been fixed

i thought it was only single GPU micro-stuttering.

No it was also 2 cards I believe. What I know is that the AMD cards were stuttering pretty bad single and dual card. When I updated the drivers, it fixed the stuttering.

If you have a case and motherboard that permit you to put two cards with a decent gap in between (at least one free slot between them, preferably more) then go with the 7790.

If not, I'd seriously advise the 690 (or whatever the current dual-gpu AMD card is), otherwise you're going to end up driving yourself nuts for a while trying to get the top card to cool properly, then eventually you'll drop a ton of cash watercooling them.

what about the just released Geforce Titan? if you are considering a gtx690, that means you have the money. a single card is always the least problematic, right? it would be about 60% faster than a GTX680. yes, not the same as a GTX690, of course, but you probably will "feel" the same FPS.

Neither do I. just look at the graphs. the 7970 is showing a lot of frame latencies. GTX680 is much smoother.

Not all micro stuttering has been fixed. Single-GPU microstuttering has been greatly reduced on DX9 games.
A new video memory manager is supposed to be released to fix microstuttering amongst DX10 and DX11 games.
Dual-GPU microstuttering exists in both AMD & Nvidia, it's supposedly worse on AMD tho, IDK if the newest AMD drivers affected dual GPU's in anyway.
The GTX 690 is two scaled down 680's put in SLI, since the 7970 is the direct competitor with 680 trading blows with it, the 7970 in Crossfire should beat 690, especially when overclocked.
I'm not sure if a 700W PSU would be enough for oc'd 3570k + 2 oc'd 7970's, might want for confirmation on that one.

I'm with skorpian. I would reccomend a 900-950w psu

And yea it did significantly improve micro stuttering in Crossfirex configurations.
