As I said, 25-30% is realistic. Any more than that is wishful thinking due to the reasons provided in my last post here:
And you can't discount the reasoning there. If the 3650 was 256-bit the score would be around 6.5k, which would make the 3870 score with almost 300% the shaders (and double the TMUs AND triple the ROPS !!) of only 10k completely incompetent, so you can see only 50% more shaders will not have a huge effect. It's called diminishing returns, look it up.

I have my reasoning for my estimated score, I would like to see yours.

Imo your reasoning is flawed here. There is no way to predict the effect of a faster bus on the 3670. There is no way you can know whether its lack of TMU/ROPs is going to allow it to have anything more than minimal gains from a faster bus. Additionally what the 4870 should bring is improved real world gaming performance as it seems to address what appears to be the biggest bottleneck in the R600 architecture for many games
