If you have got £40 spare in the budget then why don't you go for the AM2+ Phenom II X4 940BE??
It is clocked 200mhz higher and has an additional core too. The processor is on today only too!!
The processor is around the same speed as an Intel Q9400:

The stock cooler for the Phenom II X4 is pretty decent too and there is no need to really an aftermarket cooler unless you intend to do some serious overclocking:
