October 1 was the release date for both the nForce 2 chipset from nVIDIA and the Athlon XP 2700+ and 2800+ from AMD. There are quite a few reviews up now, so i will give you links to most of them.

First up we have the nForce 2:

AMDMB.com's review of the Asus A7N8X nForce 2 board

Anandtech's review of the nForce 2

Hexus.net's review of the nForce 2GamePC's review of the nForce 2

Next up we have the XP 2700+ and/or XP2800+ reviews. A lot of these combine an nForce 2 review in them, or at least a small look at the nForce 2, with benchmarks, which explains the rather small number of plain nForce 2 reviews.
