CPU : Personally id change down to a FX-8120 the benefits of a 8150 are small and you probably won't notice.
Memory : 16Gb of ram ? It's upto you, if i was rebuilding again i would go for 16Gb's as i do a lot of rendering. However 8Gb's is fine. 1600 - 1866Mhz either is good ( little difference )
PSU : The FX cpus are power hungry under heavy load, add to the fact that down the road you may get a better graphics card, id get a better PSU of 650w at least if not higher 700w. Make sure it is 80+ certified if not better as you want optimum power under load not idle. So 500w 80% eff = 400w hence 650-700w 80% eff = 520-560w real power.
Cooling : If you do go for FX cpu then you will need to keep it cool as SOME can run rather hot under load.
Motherboard : Look around and see what other boards are available for price range or slightly above, as it's the most important part of your build id be defo sure i get the one that is most suited and reliable.
GPU : The 560Ti is still a good card, but if you can get better then do. The 7800 series offer good performance for power/price, or go Nvidia as good as you can afford.
SSD : Ive had many and always found 64Gb is never enough, if you can get a 90 or 120-128Gb one while prices are good !
Anyways , the only two things i wouldn't skimp on are PSU & Motherboard as i see these as the most critical parts to any build. Just my
