New/building computer doublecheck

[Niteflier]

I guess the topic might have been clearer, but I'm looking at buying/building a computer for myself from newegg.com for gaming, since my laptop has taken to overheating and shutting down while playing CoX.

This is what I've picked out, but I'm not exactly certain if it will all 'go together' once I'm able to build it. I *intend* for this setup to last 4-5 years before having to upgrade again.

Any advice/cautions/warning will be greatly appreciated!
