i currently have an amd 1800xp, 1 gig of mushkin pc2100 ram and an epox 3kha+ board. the motherboard died yesterday and i need a new board now and i'm debating between the dfi nf2 ultra infinity board, the Abit NF7-S v2, the asus a7n8x-e deluxe or the epox 8RDA3+ (i think i might have this one crossed out now since soundstorm looks like a feature that i'd want). i'm mostly concerned with system stability but after reading the reviews it looks like a lot of people are having good luck overclocking the xp mobile CPU's which i might try. i also want to keep the motherboard cost under $100. what do you guys think i should get? should i try the mobile cpu? what speed of the mobile xp should i go with (looks like most people are going for the 2500 or 2600). thanks so much for any inputs!
