Does these fit good together?

Cooler Master HAF 912 Plus Midi Tower

Corsair TX 750W PSU <-- is that good enough?

AMD FX-8150 8-Core Processor

ASUS Sabertooth 990FX R2.0, Socket-AM3+

Kingston DDR3 HyperX 1600MHz 16GB

XFX Radeon HD 7950 3GB GDDR5  <-- can I overclock?

Corsair SSD Force Series 3, 120GB 2.5"

Seagate Barracuda® 1TB

Samsung DVD Writer, SH-224BB

I would recomend not using amd FX processors especially last gen just because of performance issues try to go for a intel option if you can a i5 3570k will out perform the 8350

Yep I agree with waffletime. But yes the PSU is enough.

I've got an AMD FX-8150, and Asus Sabertooth mobo, along with the same 750W PSU. It runs fine, but extremely hot, and it's not even worth trying to overclock because of the heat and you really dont get that much more performace. I wish, now, that I would've gone for the 3570k or 3770k, instead.

If you pick an AMD, go with the 4300,6300,8320,8350 They are newer and abit better than the older bulldozer.

I say support AMD, its the smaller company, instead of Intel, if you are performance hungry sure Intel ftw...

last gen?????

if you mean bulldozer, then yeah.

vishera is alot better. get an 8350 or 8320
