If it is good quality RAM, it is not slow, I have a K7 700 with bus at 100 MHz (old MoBo) and runs fine, better than P3 with 133 bus. About cheaper, I would have to check, 700 price is going down, it was down when I got mine, so now...

One thing is true, if the OS can handle multiple CPUs, you can run multiple process at same time. So if Gimp requests a X thing and then keeps working at its own things, both will be done at the same time. Or if your machine is multiuser (I have some that do that), or like to compile in background, SMP is also good. IIRC there was some notes somewhere about optimizng for SMP, so maybe some tasks can use two processors. Plugins run as separate processes, that is sure, so you can run two full speed things at same time (different images). You could check the source or CVS for info (look for changelog files). GSR
Re: Dual processor
The dual processor part is handled in the kernel. I have a dual PII 266 Mhz which I am very happy with. Linux does a great job handling the two processors equally. I have done tests and my dual PII 266 goes about as fast as a PII 450 Mhz single. Part of that might be because I am using an IDE drive and a 33 Mhz mother board. Other than that I have been very happy with the performance especialy when it comes to doing graphics manipulation. Mogens Jæger wrote: Hey there.

Re: Dual processor
While that is correct that multiple processors are handled by the OS itself, assuming this is the entire answer is incorrect. The Application itself has to be written to take advantage of this function. Unless GIMP has multithreading built into it, it will not take advantage of multiple processors, even if the OS can.
