If hyper threading is needith not, doith as Andiron hath said, and get thee an i5. Seriously though, if you don't need the hyper threading capability of the i7 there is absolutely no reason to step up from the i5, i5 speeds are just as fast they are just a step or two down on how well they handle that many more processes at once. I'm not a photo shop guru, but I don't believe there is much of anything an i7 will give you an i5 wont as most of what you'll be seeing/doing will be gpu driven. IOW, save the cash difference and put it into a better video card. Also if you have no desire whatsoever to ever even consider overclocking, save a little cash and don't bother with one that has the capability(K designation for intel).
On RAM, 16gb never hurt no one. But on the flip side, 8gb may well be enough it just depends on what she is editing and how resource hogging it'll be. My advice would be get a mobo that will accommodate plenty of ram and then put as much in there as the budget will afford with 8gb as the basement. If you have to start with 8 and upgrade to 16(or more) later, nothing else in the build is going to be as cheap and simple to upgrade later as the RAM. So if my budget said 16gb of ram and cheaping out on the cpu/gpu/mobo or going with 8gb and being able to get the better cpu/gpu/mobo I'd go with the 8 and revisit it later. Often over looked speed on the memory is important, not just the overall size.
SSD, there's little reason not to other than price. The price isn't to bad these days and it does indeed make for faster loading. So get one big enough for your OS and it wouldn't hurt either for it to have the room for your frequently used programs. But, on the flip side, it's also going to save you nothing but a bit of time. So again, if it meant having to cheap out on the cpu/gpu/mobo, I'd ditch it and wait the extra couple seconds for windows to load or a program to open so that I could have better performance when using the application.
On the card, I like EVGA cards. With what you are wanting do not cheap out here or it's going to be your surest bottleneck. Look at the 9 series, something like an EVGA 970 superclocked offering should do well for you and (double check the specific card) can be SLI'd with a second card later if needed.
As to the fans, you want quiet? You want good? Noctua fans. Also ditch the supplied CPU fan, keep it on the shelf as a spare, and drop the 30ish bucks for a Coolor MAster CPU cooler (that can keep the fan it comes with).
I'd take a good look at what she's doing and see just what her base requirements are. 1000 might be a little low, might be way low, or it might be perfectly realistic. Just off the top of my head I'd say 1000 might be doable but you'd be much better set by adding a 2-300 on to that. Better to suck up another 2-300 than "waste" 1000 because it wont do what you need it to. All depends on just how intensive the photo editing she is doing is. Also keep in mind the real beauty of this, upgrades. Set yourself up will now with a good mobo, good processor, a 2 way capable gpu, and an overkill PSU? Six months from now after having the chance to put another few hundred bucks together and examine if it has any deficiencies and you can very easily toss in another serving of ram and a second video card to run in SLI.
