Currently using and old machine and looking for some advice on upgrades or possible new build. Have not built a machine for a long time so out of touch with the tech.current machine is a HP pavilion family: 103c_53316j product name: gu661aa-abu m9070.uk
Currently using
Q6600 quad core2.4 ghz
3gb ramddr2 333
Win 7 ultimate 32bit but can upgrade to 64
Nvidia geforce 8500 gt 512mb
Motherboard - Asus ms1c7br70505966
Hard drive - 500gb and 2 external 500gb for backup and storage
Display - Philips FTP 1920x1080 28inch
Have peripherals but would like new gaming mouse and keyboard if not too expensive
Also have some components that were given to me but I know they not great but may be of use to keep price down
Motherboard Asus p5g41t-mlxwith 2gb DDR ram
Gpu - radeon hd5450 1gb
Would love to keep to a budget of about 600 but can and probably will be persuade to spend more if its worth it for noticeable stability and proformance. Not built my own for a long time but could give it a go if upgrade is bet option, otherwise new machine would be nice. Mainly used to play WOW at the moment so graphics not a huge load but want to be ready for the MOP increase in resources.
Thanks in advance
