New AMD CPU & Motherboard?

[sep]

I know the question has been asked several time, but not by me. I?m currently scrambling to get a replacement board for my fried DFI PA61 (Slot-1) motherboard to run a Pentium III 550E CPU. I was looking at three boards to get, Asus P3B-F, Asus P3V4X or Abit SH6, but I?m having no luck on the Asus and the SH6 cost about $140. When I?m done I?ll still have a Pentium III 550E and would of invested this money in to an outdated system/architect. My questions are:

A) What is a good/stable motherboard to support a Duron, Athlon or XP without all the options (RAID, Sound, Lan, etc.)? I want keep the board and processor close to the above price. Optional would be the ability to use SDRAM or DDR.
B) Will I see a big difference from Duron to Athlon of the same speed/FSB?
C) Will I see a big difference from a FSB of 200MHz to 266MHz?
D) I want to get a retail CPU. Will I have problems OCing the retail vers the OEM later?

I leaning towards a Duron 850, but don?t have a clue what motherboard. Please help!
*Board should be upgradeable to at least the XP Series

Thanks AMD GURUS. This will be my first time doing an AMD?be gentle!

Since prices are great and you aren't in need of the Fastest CPU, I suggest the Shuttle AK31A for 80$ or the K7S5A(if you really want bothSDRAM&DDR support) for 57$ and a 1ghz T-Bird for 78$.

Well, I'm enjoying total stability on my A7M266, but it's currently $140 to buy. I would say a real good budget board is the ECS K7S5A, round about $50-80. I've heard a lot of people with success stories using this board.
