Cheapest Dual Core upgrade for your Intel 775 mobo

[thrunner]

Intel has released the cheapest dual core CPU in the Pentium D 805 for about $145 (see any of the mail order supply http://www.mwave.com, www.zipzoomfly or newegg).

 

If you have upgraded to the Intel socket 775 motherboard that is compatible (edited: 945, 955 & up; 915 and 925 do not support dual core), you should be able to use this chip which is nearly on par with the Pentium D 820 and 840. http://www.hkepc.com/hwdb/pd-805-2.htm

Intel Pentium D 805 (2.66GHz 1MBx2 L2/533MHz FSB)

Intel Pentium D 820 (2.8GHz 1MBx2 L2/800MHz FSB)

Intel Pentium D 840 (3.2GHz 1MBx2 L2/800MHz FSB)

 

Here are some benchmark on an Asus P5LD2-VM, 2GB DDR2 at 588Mhz FSB:

Do you have a comparison to see the difference between Duo and Single core?

Do you have a comparison to see the difference between Duo and Single core?

I guess it would be something like this: http://db.xbench.com/merge.xhtml?doc2=151511

You can also read this chart:

where you see single core rendering of 251 vs multi-cpu rendering of 458.

btw the dualcore 805 is overclockable to 4.1ghz with minimal cooling ok 3.8 with air cooling and 4.1 with a basic water setup tomshardware did a writeup a day ago on it..
