I've been using a G5 for upwards of 1 1/2 months now, and I tell you, it works great if I'm not in a hurry.

If I need to get something done quickly, it has trouble keeping up. But it is quite tolerable.

This is a first gen DP 2.0 GHz, by the way. I have a Quad, but the LCS is out for repair, otherwise I would've used that instead (and probably would've had a better experience).
