more or less anything you'd want to support have SSE2... it's part of the AMD64 ISA and it replaces mmx, 3dnow, and the x87 FP instructions as a matter of fact. It's also supported by all netburst CPU's, all the intel M cpu's, the C7, etc... this decision does leave out anyone with a pre-amd64 athlon, or pentium3 users. If you're willing to risk that architectural decision, then that's up to you, but do keep it in mind that you're leaving out some users at the trailing edge of tech. this may be okay because the machines in question may not have enough ram to support solaris comfortably, esp. with KDE running, but that's up to you.
