How much of a difference is there between these two cpus?

[rally]

I have an Intel Pentium D 2.80 GHz Dual Core CPU SL88T that I pulled from a Dell that somebody spilled liquid on top of the unit and it trickled down and I think got the motherboard. I got it to boot once and that was it. The CPU looks good with no signs of damage. I am trying to build a cheap system to replace my laptop I was going to use this Motherboard http://www.google.com/products/cata...&ct=result&resnum=3&ved=0CBEQ8wIwAg#scoring=p

And this cpu: http://www.newegg.com/Product/Product.aspx?Item=N82E16819116091

My question is how much of a difference in speed is there between the Intel Pentium D and Intel E6300? Also the Pentium D will fit in this MOBO right? And if there is damage to my CPU (the old one) is there anyway it can mess up the MOBO?

It would save me a decent amount of money to reuse the old chip. I am just looking for a little of an upgrade from my laptop for occasional microsoft flight simulator use.

Thanks

I think the difference would be pretty slight. It certainly wouldn't hurt to use that used cpu first and see how you like it (barring it works). The only difference between the two is the FSB (800 vs 1066) and the manufacturing process (90nm vs 45nm) meaning the chip you have may run a little hotter than the E6300.

If it was me, I'd use what I had on hand.

Ok so it won't be that noticeable.

And no chance of burning the new mobo?

I was thinking of going with this mobo instead this will work right? http://www.newegg.com/Product/Product.aspx?Item=N82E16813131399&Tpk=ASUS P5G41-M LE

I am guessing anything LGA 775 will work?

I'm super busy right ATM, sorry.

If you can afford it, look for a P43 or P45 Chipset for LGA775 at the Egg. They just tend to be better overclockers (if you'd like to keep that as an option).

As for burning the MB, I doubt it, but I haven't a clue.

Can I just get a basic cheap $10-20 heatsink fan? The case is going to have two fans on it.
