Hello, I had someone from this website help me build a computer for gaming, which I would be buying around Christmas. I made some of my own adjustments to it, and I was wondering if I could get some advice on it.

It's good but the mobo is too expensive :S

Also the PSU is quite overkill, 500W would easily suffice.
