I've been saving up for a long time and have done a ton of research, but I am worried that I could do better on the mobo or case. I also am curious if the power supply will be enough if I want to crossfire in the future. I will obviously game on it but I mostly want a dependable computer I can count on for a while. I am also curious as to what connectors, mounting brackets, and other miscellaneous hardware I might need. Price is flexible and I have no brand loyalty. Thanks everyone!
Your build is fine except the PSU will be pushing it if you intend to X-fire, PSU's degrade with capacitor aging. Also if you are using the rig for only gaming an i5-3570k will be suitable as game don't benefit much after an i5.
no 650 might hit the wall try going 750 watts or more. and you also don't need a 80plus gold PSU unless power is really expensive at your country. also if you wanna save some cash id recommend core i5-3750K for the best bang for buck. but if your doing other tasks like video editing or something core i7 is the way to go
