Upgrade advice

[Timscape]

I want to upgrade from my Gigabyte Ultra Durable 3 EP45-UD3L

I know I may need a new CPU, faster hard drive, updated RAM.

Maybe I'm talking about a complete new machine?

CPU: Intel Ciore 2 Duo E7 400

8 GIG RAM

OS is Win 7 64

Any suggestions?

Thank you very much.

Need a firm budget to start. Vender preference? I use newegg.
