There's plenty.  It seems to perform about as well as a 7970 GHz.

AMD for Price / Performance / Power Draw. Joined PC gaming late (this gen). My first card was a 1GB 5670 HD GDDR5 which was great for 7th gen multiplats at 900p. Got a 2GB GDDR5 7870HD last year for my 24" 1080p panel and loving it. I dual boot Windows and Ubuntu and have never encountered any driver/software issues nVidia fans like whining about. My next card will be AMDs next 4GB mainstream card, not the R9 series as it only has 3GB (not worth it just yet).

R9 has 4GB.

Mainstream not High End card. The 4GB R9 will be way to pricey for me I hear $700+, hell to the no. Im sure the R10s or whatever will hit the sweetspot whenever they launch. As for now the 7870 will do.

The R9-290 will probably be ~$500.

I pick AMD because it gives me better performance for the same or less. I would definitely pick nvidia in my next build if it gives me the better deal. I also trust AMD more because I or my friends have had problems with almost every nvidia card they've used. And I've never seen an AMD card break, and I've actually been much rougher with my AMD 7950, which I've had for over a year, I do high overclocks on it, and I increase the voltage as well. My nviida 560ti broke in about 2 months when I barely even touched the voltage.

I expect more once SteamOS and Mantle go live. Thank goodness really.

Of course I don't make money out of folding, I do it to potentially save lives and to advance the human race's knowledge of disease, if anything it costs me allot of money, electricity ain't cheap and my PC isn't exactly sipping it.

As for Bitcoin mining, I mean Bitcoin mining, yes ASICS like the one's from Avalon will out-perform me, I do about 2100 mh/s, where-as an ASIC will do around 60,000+
But, ASIC's still aren't common place so it's still very viable for me to use spare compute to mine some coins. (Which converesly ends up being donated to charity.)
Once ASIC's are more common, then Bitcoin mining is going to get more difficult.
One day I might build a dedicated PCI-E ASIC box for it, once Monarch BPU's are readily available.

The point of it is, I run a 7680x1440 screen set-up, nothing less than multiple high-end cards can push gaming at that resolution, but instead of when I am not gaming or working... I might aswell put those compute cycles to work when I am not using it.

Doesn't it like take more money to mine with a gpu rather than using an ASIC to get more coins than using electricity ? ^_^

After all ASIC's are much more efficient at performing double SHA256 functions than GPU's ever could hope for. 

If I were you I would move into litecoin mining because it depends more on memory subsystems rather than integer performance. Plus AMD still dominates there too since they have the better memory system too. :P

If I was worried about electricity, I wouldn't be bitcoin or folding at all.
I still make money.
