Sudhian Forums - Shuttle SK83G. Shuttle announces their next Athlon 64 machine. Uses a variant of the VIA chipset that has integrated graphics. Not clear how well it overclocks. It uses the older 754 pin socket, so most discussion is about whether to wait for the upcoming 939 sockets that will come in May.
So, if you can hold on a few weeks and the 939s should be here.
