The ASUS A7V133 PCI slot is not THAT big of an issue, since chances are you will get irq sharing problems long before you finish using up all the slots. From what I understand, the board only has 4 irq's to share among its slots, so more slot just means more cards to collide. However, I do hate the way Asus tied slot 4 and 5 (and USB) to the same irq...
Aside from the the A7v133 seems damn stable in comparison to the KT7A. Seems like the KT7A (not sure about raid...) have issues with having DVD/CDR drives on the second IDE channel if you have SBLive (I had experienced this first hand). After exchanging the KT7A for my A7V133, must say the problem went away for keeps.
btw...is anyone noticing A7V133 is a bit finicky on WinModems? My cheapo PcTel winmodem was fine on my Kt7A, but on the A7v133...it is acting up with weird sound and crap.
BTW...that KT7A "revision 2" thing sounds like the reviewer is looking at a "golden" board to me. Chances are, the board for sale to us common folks will not go THAT high.
