As I mentioned, clock speed is only one difference. The cache is not the same, and from a bit of research, it looks like the E5 has double the memory bandwidth over the E3, so it's not at all a trivial difference.

What would make you think that? I just want to see an actual comparison, not comparisons with parts people think are "close enough". Maybe that's impossible right now, in which case I want people to stop trying instead of coming up with "close enough".
The question is, how much does it cost to build a PC "with the same parts"?
