I use Micro Center all the time here in MD. GREAT prices, but yes, most of the good stuff is in-store only.
I was trying to get the District Manager to OK someone too far from a Micro Center to be able to take advantage of those prices, but just could never get a hold of the guy and ended up giving up in frustration after trying for a couple of weeks.
But if you can make a trip there, FABULOUS prices on computer parts AND on HDTV's. I picked up a 46" HDTV for $329, and use it as my primary computer display.
I used to have a 6-core AMD processor, and it ran everything just fine, but I find the i7 chips to be faster. AMD is still GREAT bang for the buck, however. Micro Center usually has AMD CPU/Motherboard bundles that bring down the cost of the motherboard to next to nothing - even if you upgrade the motherboard they give you something like $40 off.
