Okay I saw a E6750 and E8400 dual core processor for really cheap. Like $179.99 and $204.99 respectively. However my motherboard can't run those so I had to downgrade. My motherboard can run E6700 and lower. However these are $300.00+. What the heck? I thought more advanced technology is more expensive. There's also a quad-core which I can run(thank god0 and it's only $219.99. Can somebody explain what's going on here?9And power requirements for the Q6600?
