Thanks for the quick replies! The TRU Bolt Thru kit is actually cheaper than the Xiigmatek crossbow kit, although it's backordered

. I saw some reviews this morning on Toms and Anandtech about the Phenom II and yeah, I guess the Q9550 won't drop that much too soon. So I think I may just go ahead and order this afternoon!
About the MIRs, I've never had problems in the past but then again, I've never done 4 at once. I do realize it's more upfront but I think I can manage it. Hopefully I can get free shipping...
Oh yes, and I already have vista x64
