• Happy holidays, folks! Thanks to each and every one of you for being part of the Tom's Hardware community!

Which build should I go for?

Solution
yes, absolutely fine, change the PSU to XFX TS 550W or XFX PRO 550W , Seasonic 500/520/550W or Antec 550W and you are all set :)
first 2 builds: get another motherboard: Gigabyte 970A-UD3P. The Asrock is not good at all, it cant handle the load of a 8-core FX.

for all 3 builds, get another PSU, XFX, Antec or Seasonic 550Watt.

Rest looks great, what are you going to use it for? If gaming only i would pick the Intel build, for gaming and heavy threaded programs the FX8320/8350 build!
 


+1 for the Gigabyte motherboard recommendation. (* See my sig )

For gaming, you won't see much difference between an i5 system and an FX 8320 or 8350. So just go with whichever you are most familiar with or whichever is on sale.

If you go AMD, remember that the 970 chipset boards don't crossfire well, they are good for a single high end GPU. But most gamers will recommend a good single GPU anyway.

If you go Intel, try to get one of the new Devil's Canyon i5 CPUs. Better in every way over Haswell.

For both, go for good aftermarket cooling and throw a mild OC on it and you'll be happy with the results. :)
