After this discovery of little performance gain between the 8305G and the 8705G, expect one of the following from dell, other manufacturers or intel/AMD:
1) phase out one of the two offerings. If 8705G - marginal performance gain, higher cost than 8305G, can't sustain performance advantage. If 8305G - cost the same to produce as 8705G
2) Manufacturers offerings/pricing greatly change to: 8305G only offered with 8Gb ram with higher price, 8705G with 16Gb with not much price difference, or only offering one of the other with the higher price point.
3) Intel selling their 8305G much higher or cutting back substantially on its production, while trying to balance the sales of it with the 8705G.
Whatever the outcome, I don't see it as a win for the consumer. It's probably best if anyone wants the 8305G, to take advantage of the cheaper price now.
