As the title states I need a bit of insight on what I should do with my comp. Should I just build one from the ground up or upgrade my current rig.

(A 775 LGA socket)

Mainboard - Dell inc. Model - 0k068d -Chipset- Intel P35/G33/G31


I Have 4 gigs of ram btw

Graphics - ATI Radeon HD 3400 series.


I Have a Nvidia GeForce 9600 GT But cant install it because my current case cant handle its 7" Goodness so yea.
