I think you mean i850... The i850 will be a RAMBUS only chipset, and much like the i840 will be Dual Channel (Needs 2 RIMMS). Via plan to reliase a P4 chipset, as do ALi. But take my advice: Go for an Athlon w/266Mhz FSB and a Ali MaGiK 1 (DDR) Chipset. THis little combo will kick a P4 1.5GHz. And don't think about the VIA KT266, The ALi is MUCH faster
