FYI: nVidia 6600GT I picked up a 6600GT myself. Primary reasoning was to get the COMPONENT output to drive my older HDTV without the need to purchase an external scan converter. Cost of the alternative configuration was close enough that it was worth it to me. HDTV Processing is not a significant improvement however, over my 5700, but with the COMPONENT out, there are way fewer motion compensation artifacts.
It also has Deinterlacing capabilities onboard though it doesn't appear as though the current nVidia drivers can actually use that feature. If it can, I haven't figured it out yet. :) I also run a Twinview (dual-head) configuration and this card seems to field that processing much better than my 5700 did. It has a few other features in CINEFX 3.0 that the 6629 driver also does not appear to support yet, but maybe someday,.... ;) -Blair On Monday 14 February 2005 17:10, Brad Templeton wrote: > On Mon, Feb 14, 2005 at 10:39:22AM -0600, Neil wrote: > > Brad Templeton writes: > > >On Athlon-3000s people typically see about 80% usage.
