We have done some tests running Blender and in fact the 64bit version didn't have much of an advantage in performance. If you are not going to use a lot of calculations with large numbers or need a lot of RAM, the 64bit system will not bring you a whole lot of benefit, only problems with some 32bit-only applications people like to have (e.g. Flash plugin is 32bit only, Acrobat is 32bit only, etc.) Applications need to be specifically optimized for 64bit code to really feel the benefit, not only recompiled by 64bit gcc. You can see for yourself here: http://www.eofw.org/bench/ Comparable hardware scores very similarly, whether it is running 32 or 64bit Linux system. Also, regarding OSG the 64bit system doesn't seem to have much benefit (or bad impact for the matter). It behaves pretty much the same as my 32bit machine and the performance is comparable.
