out of topic: no-one cares about non SSE2-capable CPUs for a many years. I'm personally have some fights with ATI about 7 years ago - I have a BSOD using AthlonXP CPU and their's drivers, so I've found where and why exactly it happens, patched this error in drivers (very wrong CPU type detection) , described to ATI how it can/must be fixed - and nothing in result, well, because they dont care.
so I suppose owners of such old PCs have only choice to stick with old software versions. or upgrade.
