Im so chuffed with my system now  

. I just overclocked my 2500+ from stock 1.8ghz to 2.2 ghz. Its running like a dream. Heres a nice comparison between the old and new speed:
Benchmark AquaMark3
Before overclocking and new graphics card:
GFX score:	1776
CPU score:	5669
AquaMark score:	
15358
After overclocking and adding the 6800 GT
GFX score:	7440
CPU score:	6592
AquaMark score:	
47562
Thats 3x as fast 

, well worth the money I would say.
