Well it's going to be the Barton next. It's out Feb. 10th I believe. After that prices should drop on the high T-breads 2700 (maybe) 2600 @ 333 FSB. 2800 hasn't been all that available as it is. Hammer is in the fall or so. Yes there are MOBO's that support the Barton out now.
I wonder why you'd consider that new of a CPU without seeing benchmarks on it though? I haven't seen any yet, have you?
I'm still learning & having fun doing it!! Trouble comes with the things you forget or overlook along the way that make it not so fun!!
