Venice 3200+ question, need advice on stepping

[honduh]

I've searched in here for what is best, but the topics were decently old so maybe I can get a more accurate answer if I make a new post. That said, I'm looking to buy a Venice 3200+, but I dont know which stepping to get. The BP is an E3 stepping, CG is E4, and BW is E6, I've heard the E3 is better for the 3000+ chips than the E6, so the same should hold for the 3200, but I couldnt get any information on the E4. I plan to OC to a 2.6 or higher eventually, but I'd just like to get the best chip now so I wont be limited at 2.4 or 2.5 in the future. The price difference is minimal for all chips, with the E3 going for $166.80, E6 at $176.00, and E4 at $189.90....all prices shipped. What do you all think?
