I think the Radeon should be able to handle it. Yah, get the Crucial CAS2 PC133 memory, but don't spend extra for the ECC modules. It'll actually slow down your memory a little since it does error checking, it's really only for mission critical servers.
BTW mafiapwr, how'd you hit 1ghz with the 700e using a 133 fsb when the multiplier is 7x? Last I checked, 7 * 133 = 931 (933).
