Have roughly £500 to spend on the main parts of a PC to play the latest games, Guild Wars 2, Day-Z etc...
Want to play them on high gfx and be future proof for a nice amount of time.
The parts need to be from www.scan.co.uk as I live round the corner and it's just easier.
Here is what I have chosen so far and need advice and if possible cheaper alternatives from the same place:

This come to TOTAL = 475.62 including VAT.
Another thought also, I have a Coolermaster Silent Pro 700W modular PSU already, is that up to the job?
Many thanks in advance to anyone that replies
