sorry this is a stupid question but what are the benefits and drawbacks between getting 2 680's/7970 in cf/sli versus just getting a 7990 or 690. my main reason is b/c i got two 6870's and the microstutter in some games is just stupidly annoying. so would better cards make that microstutter go away and if yes would you go 2 cards or go with 7990 or 690.

Microstutter tends to be a pretty big problem with low/mid range cards (like the 6870). It is much less prevalent with high end cards.

As far as SLI/CFX vs single card... it depends on what your priorities are. A dual 680/7970 setup will be faster and less expensive than a 690 or a 7990. However, they do take up more room and can be noisier. Personally, I would recommend a dual card setup as you are getting more bang for your buck.

Most show 2x 680 beats a 690.

I always go wuth 2 cards over a dual card on a single PCB.

Looks better (To me). lol Microstutter will exist the same with 2x 680 and a 690. They are still two cards

I have been running 2 PNY GTX 580's since Nov 2010 and have never had microstutter or any problem for that matter.
I had a GTX 295 when they first came out (dual gpu single card) and it was kind of a pain with both gpu's in one case as with 2 cards if one goes bad you have one still running so I would go with 2 cards vs single card with dual gpu. also I think when you run a game that does not support sli a dual gpu card lose's more performance when it runs in single gpu mode then when you have 2 cards but thats just my opinion.

From what I have read thus far about the 690, it uses hardware based frame metering for smooth, consistent frame rates accross both GPUs. I dont have a 690 my self so hearing from someone with one would be best, but it seems at though the microstutter isnt as bad as a dual card set up or as bad as the old dual GPU cards.

well i looked at all the benchmarks on most websites but none really tell which one has the smoothest frame rates i heard even if you get high frame rates but bad timing can make you gaming choppy sorry if i am kind of vague with this stuff

Just go with the Dual 680's if you can. I mean I would go for dual 680's over a 690 any day. Plus you save a few bucks, so you can also get a case upgrade.
