Lee, I've been reading that thread with interest. Thanks.
Also, at this point I have no reason to believe that I'm not 100% xrun free with the right set of apps, meaning I cannot really say any xrun I see today is kernel induced. (They may be...I just cannot say that.) For instance, I've yet to see an xrun in days of using Ardour and running Jack from a terminal. However running Jack from QJC and using Aqualung results in one or two every few days. This is a low level issue from my perspective.
My interest is, in general, audio only. However, on the odd afternoon I have no qualms about rebooting into a different kernel or a different video driver that might support a bit of game playing. That's all that's going on here. Someone recently said there might be PCI Express support in 2.6.15 so I was just looking.
That said, over the last couple of years I have done a couple of jobs that are sound track related. (Pro Tools, Vegas, etc. under XP) I'm keeping my eyes open for a tool set that might allow me a similar opportunity one of these days under Linux. (No rush at all)
Note: It may not be obvious, but I'm young(-ish), retired, and pretty much get to do what I want now. The only thing that stops me from doing this on two machines is space and noise concerns.
Thanks for all your inputs. You've been a great help.
