In a run-up to the launch of AMD's Radeon X2800 series and GeForce 8600, Nvidia has prepared a bridge between upcoming mainstream 8600 for $199 and high-end 8800GTS cards for $449. The bridge's name is 8800GTS 320MB.
Graphzilla just slapped ten 32MB chips instead of current 64MB ones and cut the price by $150 dollars to an affordable $299. The card doesn't otherwise change, we're still talking about G80 GPU working at 500MHz with 96 scalar shaders clocked at 1.2GHz. Memory clock also remained the same, 800MHz DDR (1.6GHz) yields 64GB/s of bandwidth.
