^I'd rather like that to be true, SessouXFX, but prices will adjust fairly quickly. Freesync could end up being a powerful draw for AMD. Do you know if Freesync has hardware dependencies other than DisplayPort, or can it be implemented in drivers?
My wallet-hand has a decided tremor in it these days; I'm not sure I can talk myself into a GTX970, but a GTX960 might be compelling. The R9 280X lacks AMD's newest features, and the R9 290[X] seems to be hotter and more power-hungry than I prefer, which also implies louder, actually the worst of it. There sits the GTX970, beckoning...
Main reason for Freesync, is tearing on a monitor while viewing content that is 24 fps. On a 60Hz monitor, 24fps content can tear because 60 isn't divisible by 24. With Freesync, that 60Hz monitor will be able to "adjust down" (more comlicated than that but forum comment) to 24Hz and remove any tearing / stutter for a buttery smooth experience. That's the mainstream reason for it existing (soon). This ability will have less hardware restrictions and will be open to a wider range of AMD graphics cards, so long as you are using the appropriate driver, supporting monitor (with correct version of displayport).
For gaming, a very small piece of the market, you will need the latest in AMD hardware to be able to adjust that refresh dynamically from like 9 to 60Hz as quickly as it needs to, in order to match the content displayed, and provide the tear free, smooth experience. It'll eventually open up to a wider range of refresh rates, but the first out of the gate will probably only be for monitors maxing out at 60Hz. This will most likely happen slowly, and dependent on the mainstream success of freesync.
Check out AMD's FAQ about freesync for the details. I'm basically trying to recall details from memory, and some reading between the lines, past their marketing BS. All in all, freesync sounds pretty damn cool... but mainly for the issues with content that is 24 fps, on 60Hz monitors.
