UNOFFICIAL BIOSTAR TPower I45 M/B

[LedHed]

When I first won this motherboard a lot of people swore to stay away from quads, but now I keep seeing people with the TPower i45 Q9550s running 3.5-3.8ghz which would be perfect for my rig. My question is what is the best quad to put in this board or is it still best to stick with dual cores on this model? I heard the board lacked the options to properly OC a quad like other boards, but If I can hit 3.6ghz I'd be happy with it. Do I have to get a Q9550 in order to hit speeds like this or would one of the lower model quads also reach this speed?

Anyone with experience using quads in this board please provide some advice and I'm not trying to spend more than $220. The Q9400 looks like the best deal, but with the Q9550 only $20 more I would just get the Q9550. However I don't want to buy a CPU that isn't going to mesh well with this board and that is why I'd like to hear some opinions.

Is it worth it to sell my E8500 @ 24/7 4ghz (stable at 4.4ghz on air) and get a Q9550 (or similar)?
