for watercooling it's pretty easy, if you buy the computer you want and you have money left then the watercooling makes sense, otherwise buy the best components you can (unless you really want watercooling but then our input is useless).
and no point in upgrading your cpu if it's for gaming. and you'll need to upgrade your monitor otherwise you'll just throw money out the window with this gpu (a 1070 or maybe future polaris would be more than enough).
as i said benchmarks are out so you can check them to decide. If you don't plan on overclocking save yourself some money and go for the non K version of the cpu.
the benchmarks just came out so it's your call if it is worth the extra dollars. If you're planning on gaming in 1080p and no to demanding games probably go for the 970. But your cpu wouldn't bottleneck even a 1080, so don't worry about that. (do you plan on overclocking?)
I don't know point and shoots all that well, but i know canon and sony have some really good ones (although the ones i'm thinking of are quite expensive).
Megapixels don't mean much, especially nowadays.
What type of camera? Photo point and shoot? hybrid? DRLS/reflex (will be hard for 350)? Camcorder (video camera)?
that's not the point they're not marketed as such (although intel pushes it a bit more with the last couple of generations), they're still primarily good cpus, amd when naming something apu is often putting a mediocre cpu in it.
if you simply copy pasted it's no wonder it doesn't work, the only solution is to clone your hdd to your ssd but the best practice is to do a clean install.
