Client is cash-poor, in particular, is really feeling the squeeze from the death of the dial-up industry. Saving $3,000 while still providing reasonable options for "worst case" can provide a lot of brownie points... in any event, I've done a fairly large number of hardware swaps between P3/P4/Athlon systems, and haven't had much trouble with it. When the next Opteron server comes in, after I've set it up, I'll test it out on an Athlon/64 system I can borrow for a bit and see what issues I run into. -Ben On Wednesday 28 December 2005 14:44, Bryan J.
