CeBIT's AMD focus has been on support for the upcoming AM2 processor. The SiS761GX northbridge, as shown on a low-cost PCCHIPS A33G motherboard, shows that you don't have to spend the earth to gain AM2 support. The SiS761GX chipset supports high-speed DDR2 memory and integrated graphics in the form of Mirage1 that provides DX9 support via software. Paired up with the SiS965L southbridge, it will be available soon for the upgrader on a budget.
Cheap, colourful and supportive of dual-channel DDR2-667.
