We'd really be able to help you better if you use the sticky I referenced above. But let me ask you some specific questions:
- this build is primarily for gaming? Any particular games at the moment?
- do you plan to overclock?
- what's your monitor resolution?
- where are you shopping from. Newegg?
Couple of comments from me:
1) swap out that psu for a corsair or seasonic, don't skimp here!
2) no point in 16GB ram for gaming. Even 4 is probably fine but 8 is more than enough. RAM is the easiest upgrade you can make later, save your money now.
3) you haven't listed a case yet, have you already got one?
4) once we sort out the above, we'll know what budget is left for the GPU. If your gaming at 1080p and the 650ti is the best you can afford, I might suggest dropping to a cheaper i5, a H77 mobo and use the extra $$ on a better GPU.
