Very true,
You must consider how the line cards connect to the backplane. I think that BW can very based on individual line cards. For example, if you go with the WS-X4548-GB-RJ45, then Cisco will only give you a single Gig per 8 ports. So that should give you a max of 6 Gbps per blade. I have never been able to find these numbers for the 3750's.
The problem with the connection based on the Sup is that you often see conflicting information:
I have link here shows the connection to the backplane will vary with respect to the chassis and supervisor
This my summary of the 4507R and 4510R:
4507R
4 GBPS for Sup II+, SUP III and Sup IV
8 GBPS for Sup V
4510R
8 Gbps Sup V
20 Gbps Sup V-10GE
Who really knows what to believe?

I should also note that I've seen conflicting information on that 12
Gbps number being a Full Duplex number and a Half Duplex number (I have
2 docs in front of me that are conflicting).
