high cpu usage in most games - Page 3

post #21 of 22
Your CPU usage is high because the 280X in crossfire will feed a lot of data to the CPU. A faster CPU will alleviate the usage and may increase crossfire scaling potential (= higher fps).
The CPU will often determine your lowest fps, so make sure you always run the best CPU you can afford.

great bit of info but I have some other issues at first. My motherboard broke so I'm getting b75a-g43 gaming tomorrow just to get me up and running. I'm waiting for new chips to come and will therefore play with lower graphics and back to 60Hz for now.
