What should I upgrade my HP carmel 3 motherboard to? I want it to be cheap but have quite a bit of expansion capabilites. I also prefer it to be ASUS if possible. http://h20564.www2.hp.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-c02831611 Also, I have an i5-2400s which will likely be upgraded.
