I have the feeling that if GPUs today had way higher shader fill-rates than today as one example, 512MB framebuffers might make a more significant difference.
Probably even higher than that; I actualy had D3D10 GPUs in mind. I wouldn't expect a higher than average 30% or so performance increase from those coming refreshes compared to today's GPUs.
Despite the differences between games, as I said I'd prefer to see the flexibility CroTeam's engines have in general. In SS2 - as in their former games - you can tune down to medium to high settings and not feel as much the difference in output as in other games.
