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:
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.
That's most of the reviews going around - i think - I will post more if i find them.
Edit: Damn typo's!!
