Interesting.

Makes Sense.

No... Yikes, I do not have those skills.  Assemble is more accurate.  I 
think I should start with the CPU I want and go from there. Over the 
counter retail parts.

Would it be possible to share a link?

Interesting.

I think this is Dell's business model.  They sell less expensive 
computers that do not take full advantage of the CPU ... want more pay 
more.

The first time I ran into this problem was when I wanted to add a second 
monitor and discovered I has to add a daughter board (is that what they 
are called?) then the computer was able to drive up to 3 monitors.

During this upgrade I was warned to not over do it because Dell used 300 
watt power supplies in their cheaper computers.

Dell has bit me twice (that I know of) so it is time to move on.

Thanks. I'm not sure what I would do with it.

WOW interesting.

I heard or read someplace that AMD is making better CPUs - is that true?
