Woohoo! I won my Touchsmart!

Limitations include power (35w) and fsb speed...

As noted in another thread, I am going to attempt putting a t9500 in as soon as it gets here...

I don't know if any of the quad core processors meet the limitations of the mobo or not, but I'd suggest reading up on it, and then, if you are willing to take the plunge (and spend the $$$) then go for it.

I'm not telling you anything... because I don't even know for sure which 800t you have coming, you gave a series, not a specific model... and the motherboards vary depending on which one you are getting.

From what I've been able to ascertain, it is the power available for the cpu that is the big limiter on some, on others (like my 507 that has the same mobo, named Eve by HP) it's the fsb that is the issue.

I know that if you have an Eve Mobo, you are limited to the T9500 (to the best of my knowledge from 2 hours worth of research, and it's still just a guess until it gets here and I actually plug it in and turn on the machine....)

Look, you want answers... I'll give you the best answers I can (as will others here) but please relax a little, do a bit more personal research (instead of solely relying on everyone else to do it for you) and add to the pile of knowledge instead of just picking off it...

Sorry if I come off as harsh on this, I don't mean to be...

Eagerly waiting on my new cpu...
