I would look at the DFI boards...They seem to OC better and have better reliability in terms of HTT stability and working PCI locks and dividers...
I would wait and see how the 3500+ and 3200+ do before I woul buy the higer priced 3800+...if you think about OCing...The 3200+ with a 10x multiplier should be the least you should consider. If 3ghz is in range 300HTT is a tough sell on quite a few boards....
