Yeah its better to avoid rj45 entire for 10gig if one can. It's unavoidable though for some places. e.g. A lot of consumer boards have a spare X1 PCIE slot...which is enough for 10gig if its gen4. ...but all the 1X cards I've seen are rj45 and didn't want to take a chance on seeing if a X4 sfp card can run in a 1X at full 10gig
