Well, I'm not planning on selling this machine. But your comment does raise a point I've often wondered about - is CPU speed really that important, if one is not a gamer or similar? This machine is actually only used as a server, serving (externally) httpd, mysql, php and openldap. As far as I can see, the slow CPU speed of the machine has never had the slightest deleterious effect. The bottleneck in all cases has been the speed of my ADSL connection (4Mb/s download, according to my ISP, but under 2Mb/s in practice). So I do genuinely wonder - does CPU speed matter at all, in such a case? This Asus motherboard has been remarkably resilient during its long (9 1/2 years) life. The CMOS battery expired (and was replaced) about 3 years ago; and two SCSI disks have gently ended their lives, in each case giving me due warning of their coming demise. > The question isn't so much whether it can do a useful job, as for how > long it will do so. I have often thought of replacing it, as I said. But is there any real reason to do so?
