Hallo, I currently have an ageing gaming PC which doesn't play various modern games (such as Fallout) at all well. I tend to get low FPS, glitching and about a second's mouse lag whenever I turn which is annoying the hell out of me 
Current specs are: AMD Athlon X2 4800+, Nvidia 7900GTX and 2GB DDR2. I'm thinking of going for the following:
Intel Core i7 920 OEM CPU
Gigabyte EX58-UD3R motherboard
OCZ Gold 6GB DDR3 PC3-10666C9 RAM
Asus ATI Radeon HD 4890 1024MB graphics card
Noctua NH-U12P SE1366 CPU cooler
I already have a Tagan 480W modular PSU which I'd rather avoid upgrading if possible. Do you guys think it'll be enough?
I also already have a couple of old HDDs, a decent Pioneer DVDRW and keyboard, monitor, mouse etc. so it's just the core components I need to upgrade.
I'd also like to try overclocking the above to give it a little more oomph. Is the CPU cooler a good one for this?
Any thoughts / recommendations / suggestions welcome! My budget is flexible but I'd like to keep it under / around £800 if possible.
Thanks very much for any feedback gents...
