[JAFF3R]

Sigh just lost all my writing so I'll just do dot points I guess

-7850 will most likely not bottleneck with pcie2.1 Only possibly if you overclock (which you aren't keen on). Still, Z77 is around the same price. ASRock is pretty decent in my experiences, but you get what you pay for (as in they don't whack on all these extra pieces you don't need, just what you need so pick the right model for you) which is why it's priced so well. I'll use them again and recommend them, more than likely use it in my next build.

-As others said, that RAM is expensive especially if you're getting it just because you can.

That's 16GB of Corsair RAM @1600mhz. 1600mhz vs 2133mhz is well documented that you will only see benefits in benchmarking.

Wasn't saying skimp on the PSU at all. It's better if you go closer to the amount of power you will be using (which is why 550w would be better). You've also said you don't want to run 2 gpu's at the same time, and you're limited by budget. So anything that will use more than 550w is pretty much ruled out (even the 7970 is 550w recommended, and with your budget you wont be getting dualGPU cards which would use a bigger PSU)so there isnt any point in going higher.
Any excess power will just go to waste, not be fed to the card to get more performance.

Ultimately though, it's your choice but with your budget I wouldn't be wasting money here and there (not saying skimp though, just get what you need).
