First build - please critique.

So, this was my first time ever finding parts to build a computer, and I wanna see how I did and just get a final check on everything. Mostly with this computer I'll be playing some older games like ArmA and stuff like that. Maybe some newish games that came out in 2010/11. And of course, school work.

Total price is $533.95 with shipping and not including rebates, cause I don't trust rebates.

Tell me what you think and feel free to fix it but please keep it under $550. Also, would I really need 8gb of RAM? Would I be fine with 4?

No HDD? No OS? Also, the psu's that come with the cases are generally not very good quality, so you might consider a different psu. Corsair and Seasonic are good brands for power supplies.

Yeah, sorry about that. I forgot to mention I already have a HDD and a copy of win. 7. So, other than the PSU how does everything else look?

Well, i'm not sure i'd go with that motherboard to be honest. It's really not going to give you a lot in the way of future upgrade possibilities. An ASRock Extreme 4, however, would give you 4 ram slots vs the 2 on that motherboard, as well as the ability to SLI/CrossFire Later on. Those options tend to come at a higher premium though. http://www.newegg.com/Product/Product.aspx?Item=N82E16813157293

That cpu, for $10 more you could get the higher clocked i5-2400, so that's worth looking at. http://www.newegg.com/Product/Product.aspx?Item=N82E16819115074 This CPU has an additional $10 off with promo code EMCNEJJ42 through the end fo 5/17, so if you buy soon, you actually get the better processor for the same price as the one you had picked out.

I've heard some bad things about the power color brand of gpus and i think it's worth it to look at dropping another $10 to get a more reliable brand.

Not to pick your build apart, cause i'm pretty sure you were trying to do what you could to meet a specific budget, and i respect that completely!
