Asus P5GDC-V Deluxe

Maximum Stable Overclock: 238MHz
952MHz Bus / 19% Delta

CPU Frequency:
18x238MHz = 4284MHz

Taking a quick look at the results, it's pretty plain to see that overclocking has nearly no effect on 3D performance testing. This shouldn't be too surprising since today's games are more dependent upon the capabilities of the video adapter and not the necessarily the entire system (i.e. CPU and memory speeds). But, it is surprising to see almost no effect since you would assume a faster bus speed would give some decent improvement.

Overclocking performance gains of roughly 18% benefits memory and CPU intensive processes. This would have a clear impact on those users doing activities like heavy computation, rendering, and media editing.

Environment:

	Stock	Overclocked	Delta
CPU (Idle)	9C 48F	15C 59F	6C 11F
CPU (Load)	29C 84F	42C 108F	13C 24F
System (Idle)	2C 36F	2C 36F	0
System (Load)	2C 36F	2C 36F	0

Ambient = -11C / 12F

Notes:
I was able to get Windows booting up to 243MHz before getting a no POST at 244MHz. From 239-243MHz testing was not stable, occasionally SuperPI would finish, but fail in 3DMark05 or Sandra CPU. No amount of fiddling seemed to make things stable. 238MHz was the highest stable setting for the Asus P5GDC-V.
