The Sempron should perform close to a Pentium 4 at 3 GHz.
Thanks, that's useful to know.
Am I therefore wasting time/money fitting the old 1.5GHz P4 with a 8400 GS PCI card?
I see I would also need to upgrade my PSU from 250w to 400W.
Rough cost of PSU + a new GPU is around $100 - $150.
Maybe time to get a new PC?
