the nv20 will be out in march or later next year. as for the v6k why buy an obsolete card. hrm, let see it might have killer fill rate, but it can't do half the affects that you'll need for future games. i wonder if it can do dot, it still can't do trilinear last i checked --stub function. as for fsaa, me think the radeon 2 will solve that.
as for rampage i don't expect it for a while now.
don't forget there is still the g800, great image quality, t&l unit, and a nice fill rate. not to mention it'll have a nice set of features.
for this winter, i'd say radeon 2 or g800, the rest will be "old".
