I went 1.5x. Based on what we now know, the GPU is quite a bit more powerful and capable and the double RAM should do wonders (2-4 times).
The problem/bottleneck will come in games/engines that use a lot of the CPU power or need faster RAM. Although the architecture may be updated from the older CPUs in the 360/PS3, the mere fact it is clocked so low will hinder some games.
So overall, 1.5x seemed fair.
