Asus CUSL2-C is considered to be the best. You can save a bunch of money by going to the PIII-700E and overclocking to 933. That will keep all your bussus running at normal speed. You can overclock most 700E's to 980 or more. But bios will kick your AGP back to 2x at bus speeds above 140 unless you use a bios hack. I just run mine at 980 when I want to, as hacking the bios scares me! You could also get a 750E and overclock it to 1GHZ at 133MHZ system bus, but this speed is harder to achieve (the 750 is no better than the 700) because most PIII's don't go over 980 unless you push the voltage up to 1.90V. I prefer to leave my voltage closer to stock (1.65 was stock, I use 1.70 for 933 and 1.75 for 980), as excess voltage can cause reduced longevity (to what extent I don't know). For best performance at a reasonable price, go with the CUSL2-C, and PIII 700 at 933 or 980. Also make sure you get Cas2 memory from a VERY reliable source like crucial (www.crucial.com). I've heard good reports about Mushkin offering higher performance (www.mushkin.com), but have never tried them.
