I don't want to be held back by this CPU. So awaiting your suggestions. I won't run any work units on the Sempron btw... ID: 52060 · Rating: 0 · rate: / Reply Quote

The general consensus is to have a CPU core feed each GPU, so your single core Sempron might incur a deficit handling the data requests from your dual 5970's.

Said that, a number of people see high cpu use while waiting for the gpu to return results which can go as high as 1 core per gpu. ID: 52067 · Rating: 0 · rate: / Reply Quote

You can get a decent dual core for $60 or a decent quad core for $100 on newegg. ID: 52108 · Rating: 0 · rate: / Reply Quote
