Maybe it\'s just me, but the vid card industry isn\'t as volatile as it once was. My friend who bought a 9700 Pro soon after it came out is still enjoying great framerates in modern games.
I bought a GF4 4200 for $100 in December 2002, it broke exactly 1 year later. I looked up the prices for another 4200 and they were the same. Not fluxuating more than $10.
I think you\'ll be safe whether you purchase now, or 6 months from now.
