I have heard somewhere (i cannot remember were, but i think it was in the AU PC Authority) that having say 2* 128MB ram performs better than just 1 stick of 256MB ram. I think they said it was because the CPU could access the information quicker from two sources simultaniously, than from one. However Guus, you may just have to look on the net to see if i'm correct.

I hope that information helps,
