I quickly read through a lot of this -- I have "friends" contributing to the thread. This is the sort of hassle I don't have enough time for anymore. I've stuck with Intel, partly out of a lazy desire to simplify my life a little for pursuing this hobby. The last time around, I was still over-clocking my new systems and making preparations for it as extra trouble.
But because I use my computers for more than just gaming, and because I have important files to maintain, I would keep a new build in "test phase" for at least three months before transferring my files and programs from the older system.
Tech Junky talked me out of building a new system this year, or for the time being. I've got my Media PC hooked up, tweaked and working. I've moved my two twin desktops to new positions under my desk, and now I only have a single monitor on my desk -- while I whittle away at the remaining clutter. Made a trip to the Agua Mansa county e-waste recycler today with about 10 or more lbs of cyber junk. And THAT'S an ongoing process that is going to take more time.
After all that, I dropped by Pepito's to get a carry-out Chile Verde enchilada dinner and a couple tacos. Shared it with Moms when I got home. We're all happy. And -- keeping cool.
