my friend is trying to get a new 1700+ and it looks like he won't be able to get the amazing 0319, so he's just going to get a regular 1700 tbred B. which core should he get, DUT3C or DLT3C? I thought the "U" was better, because I got in on that amazing 2100+ B deal back at the beginning of the year and I thought it was a "U". but now I'm seeing things on the contrary. which is more overclockable?
