Just look at my sig...I use an Abit SH6 815e slot one, and so far, it's stable up to 158fsb...with good ram of coursecheck it out...in my opinionthe slot 1 815e is the most viable solution,naitive agp 1/2, ata100 suport, and with slot one you have the best of both worlds..with a sloket, you can use the 370 chips, but I don't think they make a slot 1 to 370 converter..or ever will.
I could never get this speed with a bx board
