Motherboard Advice

[vinx]

So.. in the past (00-05) ive always been able to build a better PC or at least cheaper build then what was being sold at bestbuy or wherever..
I was in walmart the other day and checkin out the desktops. one for $600 the other about $900 and they looked pretty good to me lol

Question is, well couple questions really.
1) I was looking for a minimum of 2.0Ghz or better
but the MBs i see on newegg are dual core and around 1.6-1.8 (price range: 100-200)
Is that the speed of each CPU? or total? or do i need to price higher?

2) Any recommendations for a good MB manufacturer? I dont recognize most these names
(i been out of the build loop for years / keep patching up old PCs)

Or should i just save up and buy a premade? they seem like they are getting better...

edit: fyi lookin for the MB/CPU combo not just a MB
