Depends on which model. They all have software limitations due to pre Intel, but the later models are still rather powerful. I have a pair of dual 1.8 G5's running as servers, Highpoint RAID cards and 5 hard drives each and until recently I was using a dual 2.5 g5 daily and it was a solid Photoshop machine. It would match early Mac Pro's and Core 2 Duo iMacs. But the problem was lack of software so it has been replaced with an i7 Mini, which is a good bit faster at most things
