So iv been looking for a cheap solution for a system that may last for a while since my aging P4 rig has not been getting any newer. I was thinking perhaps the new Pentium D's.

Its cheap but seems modern? I know its budget and the 533 Mhz FSB is its down fall but its out for the newer boards which can support massive upgrades later on.. Sooo What im trying to get at is.. Would it be worth building a rig based off of this processor? I have tried looking for benchmarks on it but I cannot find any as of yet since it was just recently released..

If you are not going to overclock, do not get it since its 533Mhz FSB and only running at 2.66Ghz. If you are going to overclock, then try this link below...

Remember, the 805 series does not support EM64... Any P4 ended with 5 or 0 does not have EM64 while 6 or 1 does. When I get my combo last week, I was thinking about getting the Pentium D 805 for $33 more over the Pentium 4 506. Both CPU run at same frequency and same core except 805 is dual-core and 506 single core but support EM64. Dual-core cpu will have less chance to achieve high overclock. For example, you running D 805, 1 core can be overclocked to 4Ghz+ while the other one limited to 3.5Ghz, then you will be capped at 3.5Ghz no matter how high you push the voltage or give it extreme cooling. So in this case, a single core is a better choice for overclocking for you are only worry about 1 core be reach to that goal and not 2... Also you may see other can get upto 4Ghz+ with more voltage, but I highly not recommand you do so since Intel stated all 90nm Prescott has 1.55 Vcc max voltage. Anything above will lead to damage... Even I set mine to 1.5125v for 100% stability, I worried a bit myself but hey, $109 4Ghz CPU 3 year warranty, why not??

"Remember, the 805 series does not support EM64..."

Are you even sure of that ?

The URL below shows someone cranking it up to 3.7Ghz and outperforming the Pentium-D 840 that cost more than twice as much.

When Google isn't your best pal

If you get a Pentium D get the new 9 series. They use the presler core (runs cooler = overclocks better), and have a bigger cache.

Here is a Pentium D ending in 0 and 5 that supports 64 bit. I think that may only be true for the 5 series since thats when they added the technology correct?

Wow.. I expected everyone to say.. GO OPTERON!!!1111oneoneone XD Or something.. But I need something thats abudget processor..yet still has modern features.. I think this Pentium D will be what im looking for if I ever get the ballz to OC it. Thank you all for your replies! As always your a great help!

Nvm I was thinking about the 500/600 series, the 805 does support EM64T... But if you click on that link, you will see that the P4 D 805 isn't as good overclocker as the P4 506 series...

Well Dual cores are normally less overclockable friendly then its single core counter-parts anyhow.
