P-7801u vs P-7807u

In your opinion. would it be worth it to go ahead and purchase a P-7807u that has a P8600 2.4ghz CPU for $100 more than a P-7801u that has a P8400 2.26ghz CPU?

Also, does the P-7807u have a WUXGA 1920x1200 screen? If it only has a WXGA+ 1440x900, then I think I'd have to go with the P-7801u hands down.

 

I would go with the 7801u and then buy a much more powerful processor for another $200 if I wanted to have a more powerful CPU. I doubt that you will be running CPU intensive apps that require a more powerful processor. So far, it has done me well considering that I am a heavy Autocad user and casual gamer.

 

That does sound good.

Two questions then, where is the best place to get mobile CPU's and what kinds are the best to get for this particular model between 200 and 350 $'s?

Also how much of a pain is it to remove the CPU on these models to replace and/or simply put on some compound for the CPU and does that void the warranty?

 

For some stupid reason the 7807u is 1440x900 so I'd definitely get the 7801u over it. The P8600 is also not much faster than the P8400. The P9600 would be the way to go, you can get a "QS" engineering sample for about 250 last time I looked. ES chips aren't "supposed" to be sold, and early non-QS ones won't dispaly their name and stuff correctly, but the later production QS models aside from saying "ES" in the name look and function like the normal CPU. Extremeprocessor on ebay tends to have the good ones frequently.

As far as the warranty goes as long as you don't break the machine you can swap the original one back if you ever need service, there aren't any seals or anything, but if they found out you swapped then your warranty would be void more than likely.

 

Ahhh ok, cool! Are there any other known resellers or retailers that have those CPU's other than Extremeprocessor?

So, if I did need to send it back it would probably be best to just put the original CPU in and i'm likely good?

 

Not all of the P7807u were 1440 x 900. There were some with the WUXGA, I know because I have one, Its just like the P7805u's were. Some came with the WUXGA and others didnt.. Tiger Direct were selling some with WUXGA and now there just WXGA.
