E6550 Vs E6750

[nwo4life022]

i recently got the gigabyte p35 ds3r board and im in the process of choosing the processor...i want to get the new 1333 processors with the new stepping and i think i narrowed it down to these 2...how much difference is there between these 2? i wont be overclocking just running at stock...i would prefer to save the $40 to get the 6550 but if there is a big difference i would consider getting the 6750.
