Hey there ! Right now I have a Q6600 with 6 gigs of ram and a good motherboard. I am looking to upgrade to something more modern. Requirements: 1. Ultra fast windows 8 performance. When I click a PDF, I don't want to see it loading. 2. I play COD MW3 and Diablo 3. If a new COD comes out, I want the CPU to handle it too. I already have a good GPU. So, let's say 100-150 bucks for the CPU tops, maybe the same for a mobo, and 8 gigs of DDR3. What's the BEST I can squeeze out of it ? I hear at these prices, I have to stick to AMD AM3+ CPU and Mobo. Is that assumption correct ? And, generally, will I say WOW @ the parformance after I get new parts at this budget ? Coming from 6600 quad core ? Thanks for the help !
