😉 IMHO THere's absolutely no need at all to go for more than PC3200, save yourself the cash! Heck PC2700 is plenty fast enough, rem AthlonXP really don't need huge FSB speeds and the fastest RAM to deliver the perf (unlike the P4). As for branding, so long as it's a well known name I'd go for it, except for OCZ but that's my own preference.
