I currently have a quad 2007 mp, but have a possible good deal on a quad 2008 mp, and I'm wondering about the upgrade possibilities for the 2008 mp. Specifically, the 2008 quad comes with a single quad processor, but the motherboard has 2 sockets. Does the 2008 mp quad come with both heatsinks or would I have to find one of those if I want to use both sockets??? Are there any other potential pitfalls I should be aware of upgrading a 08 quad to oct???
