Finding your CPU bottleneck...

post #1 of 3
Thread Starter 
This review of Core I7 and Phenom II X4 seems to be really good.
http://www.legionhardware.com/articl...hd_5970,1.html

If I understand this correctly...

The appropriate method to test if your CPU is bottlenecking is

1) Max out your resolution and all settings.
2) Set a low frequency on you CPU overclock. Increase the overclock in small increments and test your FPS in the game of choice at a specific constant frame of reference.
3) If increasing the CPU frequency improves FPS then your CPU is bottlenecking the card.
4) Once increasing the CPU frequency stops increasing FPS then it is no longer bottlenecking and your GPU is now the bottleneck to improved performance.

Can someone check this and let me know if this is right?

Adversly keeping all settings the same if you lower your resolution from High Resolution to Low Resolution and the FPS does not improve then you know your CPU is bottlenecking.

Yes, you've basically nailed it on the head.

Keep in mind, any modern CPU isn't really a bottleneck, with the exception of freak scenarios (GTA IV and any AMD quad as an example).
