I just saw an offer (here: http://www.intend.ro/date/oferte/eu.pdf for socket 754 processors - Sempron 2600+, 1.6GHz and 128k cache at 100USD, and 2800+, 1.6GHz and 256k cache at 120USD. I wonder about the performance of such a configuration, and how good it would be to upgrade my Duron 600 to one of these (for your information, an Socket754 Athlon64 2800+, 1.8GHz, 512k cache would be 160USD)
