Does anybody know if a Dell Dimension 4600 will support a Pentium IV Extreme Edition @ 3.2GHz. I still have the original owners manual and I cannot find the answer, all it says is that it will support a 800MHz FSB. I have even tried google with no success. From what I understand this processor has a L3 cache, while my current one does not, does this make a difference? Thank You, Jesse My Maxed Out Pentium 4!

L3 cache didn't give the P4 much of a boost. The 3.2GHz P4-EE was not much faster than the 3.2C: 0-10%, depending on the application. Synthetic benchmarks seemed to make the most use of EE's L3 cache...lol. Your 3.4C would probably outperform the 3.2EE in some areas. Definitely not worth the upgrade. CPU support depends on the BIOS. Most i865-based boards support P4-EEs. But again, you're looking at a pointless upgrade.
