Best possible processor for PC

[Procalen]

I'm trying to make the best of my PC, a HP Compaq dc7600S model.

Please help me find the best suitable processor for my old PC.

Thank you !

Hi:

Below is the link to the dc7600 quickspecs.  The supported processors are listed by form factor.

The best processor you can install is the Pentium D 945 or 950.

The only difference between the 945 and 950, is the 950 supports Virtualization Technology.

Thank you!

I'm afraid 130 W, TDP is to high for D950.

Compared to 84 W of the Pentium 4 630 that is on the Sistem.

What do you say about it?

You're very welcome.

I agree, since there isn't a better heatsink you can use.

However the PD 945 has a TDP of 95W, which is only 11W more than the P4 630.
