Curiosity gets the better of me here and I have to ask, just what will you use the 990 for? Is it just to have the latest and greatest?
Well, what can I say? Except that some people drives Toyotas while others prefer Mercedes, both get you from A to B and nobody really "needs" a Mercedes.
I do quite a bit of video editing and conversion so I kind of justify the "need" for a 990x to myself that way. I also like to have "the latest and greatest" - but cdon't really care at all about "bragging rights". And I'm always curious about "exactly how fast is the fastest" - I usually get disappointed tho.
I have owned and still own quite a few of Intels "Extreme series" CPUs, once bought they're not really worth selling so I just keep them all. Not sure what to do with them but I'm sure they'll be useful one day - or then again maybe not.
Oh and in case you wonder, I'm driving a BMW and not a Mercedes
