Guideline: Gaming-PC for your budget!

[Danny]

I may upgrade my computer at some point soon.
I was hoping I could just buy one or two things, but turns out my Motherboard isn't compatible with newer hardware (such as AM3 processors and DDR3 RAM)


So bearing in mind I don't want to spend too much over 300 Euros, thoughts on this system?

Processor: AMD Phenom II X4 965 Black Edition (3.4 GHz) - 89,90 €
Motherboard: Asus M5A78L LE - 58,90 €
RAM: DDR3 Corsair Vengeance Blue, 4 Go, PC3-12800, CAS 9 - 25,90 €
GPU: Sapphire Radeon HD 6870, 1 Go - 139,99 €

Total - 314,69 €

I already have a case, a PSU, CD Burner and two HDD's.
