What price range? AMD 64 ($400-600) or XP ($100-200).
Budget end or top end?
As for overclocking forget it unless you want to go cheap (low 2000 ratings) and hope you get a good CPU. All the AMD stuff out there now is max'd on clock speeds within a few percent, not worth overclocking.
what do you think would be the best o/c mobo for a athlon xp..i got a athlon xp 2400+ right now thoroughbred i can probably get the number off the chip if u want me to..if u cud let me know if its onna the o/c'ers or jus another chip..jus need to knw which number it would be that you need..
As of right now, about the best overclocking board I've been seeing is the Albatron KX18D-ProII. As odd as it sounds, pretty much every review I've seen has basically said this board overclocks like no other. One site got an AthlonXP 2500+ up to 2449Mhz (223x11) on air cooling, which is pretty impressive. the only thing I don't like about the board is that with long AGP cards, the cards will overlap the retaining clips for the DIMMS... Also, the ATX power supply header is below the CPU and to the left, causing the cables to run over the CPU heatsink.. My roommate is building a computer tomorrow with one so I'll chip in with some info on how it goes. should be interesting to see, but I've seen nothing but rave reviews for the board, and at $96 on both Newegg & Zipzoomfly, it's a great deal.
