Yes, with 15.X IOS you will be at 90% in memory usage. We have one box 
(15.1(2)SY4a IOS) with two full feeds and a lot of features enabled - 
the memory usage is 88%. There is still room for a third full BGP feed. 
I'm not concerned about this, since even with an empty config the memory 
usage is quite high. However, it's stable and doesn't vary much.

But yeah, 6500 is not the best choice for the future.
