Ok so i'm planning on building a desktop for around $900 (without monitor) - http://pcpartpicker.com/p/JVyj - So i just want to know if you guys think it will be a good build or not or what to improve on it. I'm not sure about what PSU to get or how many watts. I will be overclocking my CPU and maybe my GPU. I'll be using the computer for some gaming at 1080p (on games like BF3, GTA, Crysis 3, Tomb Raider), and other random stuff like web browsing and homework etc. I'm also not sure if going with the 7950 would be worth it or should i just get a 7870 tahiti or something. I'm new to computer building and I've just been doing research before i buy, so if anyone could look at the build and give me advice on what to do it would be very helpful.
