Which Gaming Setup should I go with?

[Aggron]

Okay I'm on a REALLY tight budget and I'm trying to get the best gaming performance as possible.
I have some gaming builds I have designed on Pcpartpicker, I just want to know which one is the best for gaming performance. Also tell me the reasoning to your decision.

i5 and gtx970 has the best balance. Just get an XFX550 power supply instead. See http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html#xtor=EPR-8886
