Hey, welcome to TR.
The drivers are already here - the 13.3 betas include ongoing improvements but several games got the update with the older 13.2 drivers. I had a 7950 that I never had issues with and a 7850 that was noticeably better after the 13.2's
I wouldn't worry too much about drivers being the deciding factor, unless the majority of the games you play are TWIMTBP titles. There was an issue, AMD were notified - promised to fix it, then fixed it, and the benchmarks show they did a good job so everything is okay.
Nvidia have their driver issues too, and I've personally experienced more annoying issues with Nvidia drivers that with AMD drivers in the last several years. In today's article
, in fact, you can see that the AMD's between $150 and $200 get more consistent frame latencies than the equivalent-priced Nvidia cards. As someone who's currently playing Tomb Raider, Crysis 3 and Sleeping Dogs, Nvidia is the brand with the major stuttering at the moment; AMD are flavour of the month and as always this will chop and change over the lifespan of a card.
What you really ought to consider is how much you're doing gaming versus other things. In games, the cards are pretty even. In compute/OpenCL stuff, the 600-series Kepler products are close to useless. I encode and occasionally render using OpenCL, so I've stuck with AMD on my workstations but still have a kepler floating around at home that seems to provide a comparable gaming experience these days - and it has always been a comparable experience if you play with vsync on. All of these stuttering issues basically go away with vsync on, in my experience.
