[Biz.Kid09]

Good afternoon guys.
A couple of years ago i built myself a pc which i expected to last, Technology as come on leaps and bounds since then so i find myself in the posistion of needing/wanting a new pc.
I currently have
Core 2 Duo E6750
Gainward 8600gt
Cheap Case
Gigabyte G31m-ES2L
Crucial 2GB ddr2
Seagate 250gb SATA
Samsung DVD Drive
Thermaltake TR2 550w came with my case
23'' 1080P LCD and 17'' HP LCD

I will be needing:CPU,RAM,MOTHERBOARD,GRAPHICS CARD,CASE and maybe a new psu if i need one im also looking for a decent multifunction printer no more than about £40.
My main uses are going to be gaming,Arma II,MW 2,MW 1,COD WAW and Grid, Also i will be using Adobe CS4.
My Budget is £500

I have already read it ejr22 and i understand it and have been building pcs for a few years now, But i havent built anything since my core 2 duo hence me asking what people would recommend.
Well i want people to post different builds that way i can compare them, Well hopefully a few guys on here will agree on one of the pc posted on here and that is how i will make my decsion.

Edit:Thanks for that Kennysevenfold i dont need a psu or hdd though so i may use the rest of that build but just put in a quad
