I am running a P133 which I would guess is a lot slower that a lot of people here have and for internet communications is perfectly adequate and I have no need to upgrade. I have seen memory and software mentioned - I run windows 95 and IE5 and my computer has 32mb ram and 8.4gb hard disk (I had to upgrade on that for other reasons). The only other change I made was to install a V90 modem.There are times when internet communications are slow but this appears to be connected to traffic on the net rather than my computer and there are certain times when I find that switching from one of my 2 free internet accounts to the other speed up communications dramatically especially early evening (sreaming.net - one of them offers free phone calls to connect after 6pm and the service takes a hammering - it can take me 20minutes just to log on at that time).
