actually, no. motherboards still run at 100MHz - 166MHz. you can't run a motherboard at 800MHz. it's the RAM that runs at the high speed, actually 100-166MHz, biphase clock (quad-pumped), DDR. > is the AGP useful to postgresql? no, i was pointing out that the previous poster's implication that video cards will rob performance from postgresql is not valid. > lastly, what stuff goes thru the northbridge? is that useful in databases? of course it's useful. the memory controller is in the north bridge. the south bridge does I/O, e.g. ISA, PCI. -- Philippine Linux Users' Group (PLUG) Mailing List [EMAIL PROTECTED] (#PLUG @ irc.free.net.ph) Official Website: http://plug.linux.org.ph Searchable Archives: http://marc.free.net.ph .
