That's a little harsh.  It handles 10G fine...you just have to carefully 
plan your port layout if you use the [oversubscribed] 8-port cards and 
have some links that you expect/want to carry line-rate traffic. 
cisco.com has documentation online that will tell you which ports share 
capacity (and should not both be used by high traffic links).
