XP2000 vs. XP2200: Yeah.. save your money. The performance gains are marginal. And if you want to, you can get a 2000 and clock it to a 2200's speed. Buy any decent HS/F and you can do this with no problem. Even if you use the stock clock speeds, it's still not really worth it... for (almost) a hundred bucks more, the increased speed of the 2200 just isn't worth it,.. unless budget is of no concern. The 2000+ is prolly at the best price/performance point at the moment.
Pricewatch: Yeah.. you gotta watch some guys on there.. that's why I mentioned Reseller Ratings. Some of them don't show up on RR, but that doesn't mean they're bad. You can also try lookin it up on eBay and making sure you buy from someone with good feedback...
Not to throw a wrench in the gears, but if you're definitely gonna go with a KT333 model, (which I didn't know at first) then I would strongly recommend the Gigabyte GA-7VRXP. (even over the Soyo). When it comes to the KT266A chipset, Soyo reigns supreme (in my estimation)... but that's somewhat because the usual "kings of the hill" dropped the ball. (not to say that the Soyo isn't a great board) For some reason, guys like Asus and Gigabyte just didn't put out very good contenders with the KT266A chipset.
But... now that KT333 is the newest "thing", big names like Gigabyte have gotten back to making the best of the bunch. Check oat
this review for full details, including extensive benchmarks on the "who's who" of KT333 boards. If I was in the market for a new mobo right now, I would be getting the GA-7VRXP, hands-down. The last Gigabyte board I owned was a great piece of work,.. unfortuntaley, at the time of my purchase... KT266A was the "latest and greatest" and Soyo had the crown in that race.
