Are there any major design differences between the Gemini and Fixittt spirals? IIRC, somebody did some casual testing and found the Fixittt spiral and maze2 to be tied with about a degree or so of difference. When Joe's socketA roundup is finished, it'll be interesting to see the results.
On another note, both the Swifty and maze2 can be used on socket-478 platforms with little hassle. This was actually a major decision point for me when I ordered my block since I wasn't sure of my next CPU socket. Of course, I'm sure that somebody could rig a hold-down for the Gemini given the people in this forum
(I'm assuming that the Gemini wasn't designed for socket-478. I didn't see any mention to P4 systems on the Gemini and Case-Mod.com sites.)
