I got Zeph's 10.5 Rev 1 working on my system. All hardware & software seems to be working ok so far. Only issue I noticed is that when I play a video with quicktime it's real choppy. Also when minimizing or maximizing windows it's not smooth. Anybody else have this issue? I assume the video drivers are ok because i'm running 1280x1024@75hz and QE/CI is enabled.

My specs:

Asus A8N-SLI Premium (Nforce4)
AMD Athlon X2 4600
3GB PC-3200 (DDR400)
Nvidia Geforce 6600 GT 128MB
Maxtor IDE HD
