I'm shopping for a new computer to trade from and learning alot along the way. As far as desktop memory goes; I know the PC1066 RDRAM is better than the PC2700 DDRAM, but you can get 1024mb of DDRAM for the same price as 512mb RDRAM. I'm mostly using this for daytrading on two monitors. I know there's better/faster DDRAM on the way, and Intel is phasing out RDRAM all together, but I need to decide between those two memories right now.
