Bayne(aka SirJohn), of course the 3808 isn't due out for a few more weeks, but if by "general performance" you mean clean power of a similar output level, there shouldn't be any reason to choose between the two on that basis. The relative desirability of the features that each has would be the deciding factors. You may have noticed that on AVS there's considerable discussion of the Onkyo 875 which is just about due out now, and features the Reon video processor which the 3808 won't have. You might also add that to your list for consideration.
