First time PC builder. Need advice and help.

Sorry if this is in the wrong section. I am new to this site.

Hello everyone, I was referred to this site from a gaming forum because I asked about buying a desktop PC for gaming and everyone advice against that. Instead I was told to build my own desktop. So I did a bit of research, parts hunting and searching and came up with these possible builds.

This is all from Fry's Electronics next to my gfs house, so free shipping obviously as I will get the parts in store.

The thing I want to do is build a Gaming and School PC on a $500-$600 budget, $700 being the max stretch. I know the GPUs I chose suck, but I want something entry level. I don't want to skimp out on the CPU, motherboard, and everything else. I also don't need it to be the ultimate gaming machine. I can always upgrade the GPU later.

Also I don't think I chose the best motherboards for the buck. I really need help on that. Also I have 2 optical drives at home from my very old desktop(Win XP).

The most important part of a gaming PC is the GPU and power supply. Don't skimp on that.

Well what PSU should I get? I was told that anything around 500-600 watts would be fine for a gaming PC. I don't plan on building the ultimate PC.

Your PSU is fine, its your GPU that you will want to upgrade. Get a less expensive CPU/mobo combo if you have to, but don't skimp on the GPU

$30 over your $600 range, but you get a solid GPU for 1080P gaming. You can overclock the CPU a good bit, though if you choose to do so you need an aftermarket cooler, like the CM Hyper 212 EVO.
