I have 4 i5's I can test it on later 2 have 6500's one is a 3330 and the other is a mobile chip that I don't recall its number all run BB but I would have to test them using CoverFlow.
Honestly though I don't think your specs are the issue and that there must be some underlying issue. Mostly every one on this thread has a system that shouldn't be causing them issues. I run BB on a tablet with an Atom and 1GB of RAM now I won't say that the performance is stellar or anything but it is at least usable although I wouldn't attempt it with CoverFlow
Tested it on i5 3330 8GB RAM still works great.
