Yes - I can take the RAM to 1 Gig cheaply enough. So what will enable me to run Skype with video properly and play streaming video and DVDs properly? - a new graphics card? - I can get the ATI Radeon 9200 128Mb card for about £70.00.

I've also found a comptible G3 1 Gig processor that is much cheaper than the Encore G4 - so presumably I'd see all round performance improvement going from 350 MHz to 1 GHz.
