I guess it all depends on how much your willing to spend. You can notice the speed change between the processors somewhat, but they're both good IMO. If you don't want to spend as much, buy the 3800+ X2, and your option to OverClock it or not. If you have money out the Wazoo, then go for the 4400+ X2. Doesn't make much sense not to get the better of the two if you have the money.
