I currently have three socket A boards with PC133 RAM, an FIC AZ11 with a 650 T-BIRD @ default, an A7V with a DURON 600 @ 1100 (110*10) and an A7V133 with a 1.2-C T-BIRD @ 1.44G (10.5*137).
I also got impatient waiting for the next big thing with the DDR, so I've just set up an FIC AD11 DDR board with the AMD 761 chipset and 128MBs PC2100. I haven't had much time to "play" around with it yet, but so far it has performed at least as well as the A7V133. I've had a couple of different CPU's on it, the 650 and 1.2 T-BIRDS and a DURON 600, the maximum speeds that I was able to achieve has been equal to that which I got on the A7V133. The Sandra scores have been right on par with the ASUS boards as well.
In my experience this board has been a very stable and a good performer, as has the AZ11 (within the limits of the KT133 chipset and no multiplier). The AD11 has a lot of overclocking potential with the multiplier and FSB adjustments available. Given more time to tweak it, I think that there may be a bit more performance left in it.
Although I'm pleased to this point, the A7V133 still has a few advantages over it, namely the optional onboard RAID controller, and ATA100 support which the AD11 lacks, not to mention the A7V133 is a bit less expensive.
Given the still unsure future of the DDR RAM standards and the fact that PC133 will be around for the foreseable future, my advice at this point would lean towards the already proven SDR SDRAM boards, be it the A7V133 or a comparable board from I-will , ABIT or any of the other quality choices that you have today. But I think it's still a close call.
