Best gaming build for £400? I already have some parts!

[Vindaloovians]

Please just build me the best system for this price range! The parts must be from "Scan" as I'm not allowed to get it online but I live next to "Scan". I already have 4GB for DDR3 RAM and 2x500GB HDDs. Overclocking isn't important but I don't like the stock AMD cooler. I've put this together, any better ideas? Keep in mind I want to be editing and recording as well as ultra gaming!

Please suggest your own builds if you want, I heard the i3 and i5 aren't currently any different in games but when recording would the i5 be much better? I think the FX 6300 will be the way to go, don't go much over the budget please, I don't want to pay £900 for something that might play 30% better...

From what I've heard, PCI 2 and PCI 3 have basically no difference, toms did a review on it I'm sure...
