pentium D805 or conroe E6600. Advice please

WTF! Anti-Hyper Threading All the Way!!! Get a AM2 and when AMD flicks the Anti-Conroeversial Terratomorizer on, a once lowly FX CPU will warp time and space completing processes even before time began...

Wow, didn't know FX's could warp space time.......

Seriously, I still wouldn't call them lowly, far better than what I have.

Go with Conroe. Don't try to do that overclocking thing with the 805, you'll probably just end up with a toaster.

Edit: Just noticed that you said Core Duo, not Core 2 Duo. That is a different matter. Still, I would have to say Core Duo if you are concerned with just performance, but they are a little pricey.

1.21 Jiga watts is absolutely fine for an FX-64. 1.8 Jigawatts is the well known maximum, go above that and you'll end up with something in-between a black hole and piles.

Toasters are cool. You like floppy bread for breakfast?

The E6600 will cost more than 3 times as much as the PD 805 but it is one hell of a processor!

If you're looking at performance, the Pentium D 805 is a laughable chip any way you look at it. A 533 MHz FSB and a 2.66GHz clock speed, as well as all of the infamous disadvantages of the NetBurst arcitecture...

...It's only really worth noting because of the rediculously low price, and that it's about as overclockable as any other NetBurst on the market today.

Of course, note that the Core Duo (pre-Conroe, I see) will be vastly more powerful, but note that it will ALSO be significantly more expensive. However, also considering that it will also run cooler (and quieter) as well as using less power, (yielding better stability without requiring an expensive new power supply) Make the Core Duo well worth the extra cash, at least in my book.

No, no no, you're way wrong.
Go and find yourself a slot 1 pentium fo shizzle. It is teh best!!1!!11

Amazing! So those cheap little laser pointers i get for 1$ in the vending machine at the mall since they are made in taiwan i can use them to burn a hole in someone?
