The Steam survey is going to overestimate the power of the average machine because it is only sampling machines which are capable of playing Half-Life 2 (or other equally resource intensive games). The recommended machine for Half-Life 2 is a 2.4 GHz CPU with 512 Mbytes RAM. No surprise that most of the machines surveyed hit that minimum. As for "most powerful supercomputer" - that ignores that the interconnect used (the Internet) is going to be 2 to 4 orders of magnitude slower in bandwidth and latency than that used in any modern supercomputer. -Jack --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
