new proc, dual core vs. core 2 duo

this is going to be a nice first thread, but anyways here goes:

i have a prescott 630 proc right now and i'm looking to upgrade it, but i have a few questions.

1) can i put any LGA 775 proc in its place?

2) for gaming, my understanding was overall clock speed is most important. If this is true, wouldn't a 3.2 dual core proc be better than one of the slower core 2 duo procs?

I have an upgraded Dell Dimension e510 that I use for gaming, and I'm looking to get a bit more horsepower out of it. However, I'd like to avoid overclocking if possible. I'd rather not stress things.

    Only to a certain point in the past, and certainly not true in any sense at present.
  2. so, which proc family benchmarks better?

    i'm a server specialist for Dell, so I understand the differences in the Dempsey and Woodcrest XEON procs, but I've never messed with a gaming rig before.

    1. Yes. But it´s not certain that it works. You´d have to check the mainboard specs for that. There are a lot of boards that do support single but no dual core processors.

    2. You´re wrong. Even in the faded age of the P4 were people kept telling that Ghz is everything the whole AMD line was faster with less GHz. And now there is the Core 2 duo. A 3.6 Ghz P4 is slower than a Core 2 duo at half that speed (1,8 Ghz).

    Your board won´t support Core 2 duo. I´m almost 100% certain of that. You´re in a difficult situation to upgrade because you´d need a new mainboard too. And, to my knowledge, upgrading a Dell with a new Mainboard is a bit tricky.
  4. Clock speed is only useful for comparing similar archetectures (ie prescott vs prescott). Other than that clock speeds mean pretty much nothing. Many more things determine the performance of a processor such as instructions per clock cycle, branch prediction, cache size, cache type, dynamic scheduling algorithms, etc...

    The only way to compare different architectures is using several different benchmarks such as Tom's CPU Chars. If your interested in games they have Quake IV, Serious Sam, and UT2004 benchmarks.

    Your motherboard manufacturer should have a supported processors list along with required BIOS revisions.
