10 KDE user here too. =8^) I use ksysguard in the panel, with 4 CPU
11 monitors, one for each of my dual cores on each of my Opteron 290s. It's
12 quite useful, as user/system/nice is broken out on each one, and I have
13 portage set to nice 19, so I can monitor how much it's using vs. other
14 things (a lot of X updating the screen with konsole, particularly with
15 composite turned on, somewhat less with quadkonsole, which seems to be a
16 bit more CPU efficient but with fewer bells and whistles, particularly
17 per session when one is running more than one).

19 The dual 290s have certainly met and passed my expectations, with things
20 running much smoother when multitasking than the dual 242s I was running
21 before. With 8 gig of memory to go with it and quad drives in md/
22 RAID-0/1/6, I've no reason at all to complain about performance or want
23 more ATM. I'm a happy camper! =8^)

25 The next upgrade is my eyes, Lasik, then back to the computer for dual
26 flat-panels and a GPU upgrade as the prices on high resolution hopefully
27 continue to fall.
