Upgrading old system

[nick493]

Im looking to upgrade my old system. I want to upgrade the processor and graphics card and possibly the motherboard.

Current:

gigabyte ma770t-ud3p
amd phenom II X2 550BE
palit gts 250

I was considering the following:

MSI 990FXA-GD80
AMD Phenom II X4 Quad Core 955 Black Edition
MSI ATI Radeon HD 6870 OC HAWK

would this be worth upgrading or can i get better parts for the same price?

yes i have unlocked the extra cores on my processor, would i be better buying a cooler for it and overclocking rather than buying a new one?
