Also if you could let me know about the PSU and RAM, I know DDR3 isn't all that necessary and I will also be running Windows XP 32 bit but I couldn't find any cheaper deals. But I wanted to know what kind of PSU minimum power I would need, I want to try and get a cheaper one.
Well I would prefer anywhere in the range of 500-700$ with that build it came out to about $575 with tax and delivery and I haven't yet to buy my monitor. Resolution would probably be 1024x768 or higher perhaps.
Games would probably be Counter-Strike: Source, WoW and L4D2
But again I was meaning to build this for future games: Starcraft 2, Diablo 3 and Final Fantasy 14 as well as being able to handle the new Half-Life engine being developped
