Extreme budget build

I was asked to build a PC for as little as possible that could run a few games.

I came up with a PC for about £350 using:

[X3 440 @ 3.0GHz](http://www.novatech.co.uk/novatech/prods/components/processors/amdathlonx2 andx4/amd/adx440wfgmbox.html)
4GB DDR3 RAM
MSI 770-C45
512MB HD 5670
500GB HDD
DVD RW
450W PSU

What do you think? Any good for the low price?

Would 2GB of DDR3 RAM be enough, or stick to 4gb?

can easily build a intel core 2 duo for that price with a decent socket 775 motherboard, Also a gtx 260 grphics card, coming in around £90 now. cheap ass case from ebuyer cost you about £15.
