hahahah, yeah, over at XS this one guy got a KAB3E, i have only seen one so i assume its very very rare. But a 3700+ will be better than a 4000+ because with the 4000+, you only get a higher multiplier, which i believe is 12x. A 11x multi is perfectly fine. Just bump the FSB up 200 mhz and you make up for the loss in clock speed. And you get more memory bandwidth.
