Best upgrade?!

[joeyh51]

My pc has been starting to run a little slow recently so I was just wondering what would be the best component to upgrade to see the best performance increase.

Specs atm:

Core2Duo 2.5ghz @ 3.0ghz
Asus P5Q-VM Intel G45 Micro-ATX MB
4gig OCZ 800mhz RAM
9800GTX 512MB nVidia GPU

I was thinking maybe getting a new DFI MB for some good overclocking and then a ATI Radeon HD 4870?!

Any help would be great, im pretty unsure though because ive been out of the hardware loop for a while.

Cheers.

Well yeah it just seems really slow when opening new programs, loading etc. Lags in games quite a lot, even more than my laptop!

Couldn't be Vista Ultimate 64bit slowing things down could it? I've heard it is pretty ****e!
