New PC build 200-250?

[highfive]

Hi, im looking for a new PC build with around £200 budget, the only game i will play is csgo which is more dependant on cpu than anything else.

My previous machine was;

AMD Phenom II 965 BE
4GB Corsair Memory DDR2
Nvidia 8600GT GPU
Gigabyte-GA-MA785GM-US2
PSU?
I will buy a cheap HDD from eBay second hand, not really fussed on that

I like the look of the Bulldozer/Piledrivers but its been 3 years since ive owned a PC so any help is appreciated.

Thanks,

HP DC 7800 775 Socket Mobo
Processor: Core2Quad Q6600 @ 2.40GHz
-Memory: 4GB Installed.
-Hard drive: 500GB
-Graphics: AMD RADEON 6570 1GB -- DDR3 PCI-E x16

Could i better this?

brilliant, thanks mate. may post more questions but you rested my mind on building my own instead of some deal i found on ebay that looked pretty good.
