if you put lots of expectation on x48, then you are gonna get lots disappointment again, think about x48 is MERELY hand pick version of X38, so why bother:)
The question is - how did X48 been picked? Better OC capability? Or just for some other reasons? Somebody still thinking X48 supposed the better OC toys, hopefully the new testing board GA X48-DQ6 can prove this point.
