RDRAM uncertain future vs. Dual Channel DDR

[galtsfan]

While lurking around this very informative forum I have come to an important decision...Memory bandwith is the bottleneck for modern computers....RDRAM is a quick fix but it's future is still cloudy...DDR is available now but doesn't offer the memory bandwidth of RDRAM...Dual Channel DDR is compatible with the current DDR memory modules...but isn't available yet...I'm going to buy DDR MB that can access DDR 333 now...any suggestions...what other boards are out there that will do this, besides SiS645DX?
