Need a new desktop

[XILLAX]

kay as I'm not experienced with putting pc's together, I'm asking for some help here.

My budget is £800-£900 MAX
It has to run games such as css and newer really well
And overclocking isn't an option as I'm not good with pc's

Thanks in advance.

This would be quite good:

It's got the best graphics card you can get, the best processor (reasonably speaking) you can get, a good PSU, a swanky case, a fast hard drive, and a good future-proof motherboard.
