The 3:1 and 2:1 are the ratios between the processor speed, as given after "G3/", and the speed of the special bus that connects the backside cache to the processor. Of the three cards you listed, the backside cache bus speeds will be 133 MHz, 200 MHz and 225 MHz, respectively. Also, although I have no personal experience on which to base a comparison (I'm using the last of the three and have never tried any others), it's generally said that there's a big difference between a 512k backside cache and a 1 MB one. For both reasons (cache size and cache speed) you should rule out the first one you listed unless you get a better price than $95 on it. The choice between the last two is an obvious speed/price tradeoff, so you can decide how much an extra 10% (or so ) speed boost is worth to you. BTW, I am not a Photoshop user, but I understand that it's one of the programs that make good use of the multiprocessing capabilities of the G4 processor. You should probably look into it before settling for a G3. - Aaron -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
