Question best Old LGA775 cpu

[.valkyrie.]

hi, i need to build a temporary pc with my old P5Gz.. all i got is this MOBO and a 2Gb ram.
i need to grab a cpu for this build.

i believe this is 945 Mobo with no quad support.
around the web i saw 2 comment that people could boot it with Q6600. is it even possible ?

what Cpu would you recommend for this?
i was going to grab a pentium d 960 for 1€ since i believe those with fsb 1066 or above wont work on this chipset

Have a look at this chart;

The best consumer LGA775 chip?
Core 2 Extreme QX9770

The best LGA771 chip (which can be converted to work on LGA775)
Xeon X5492

A really good chip, no matter if LGA771 or LGA775 with great overclocking potential?
Xeon X5470

The best that works on a board with 945 chipset?
Core 2 Duo E4700
Or in general the E4000 series.
The Pentium Dual-Core E2000 series will also work and perform decent. The main difference is that they have only half the L2 cache. But at that point, a higher clocking chip will give you more than one with more cache.

But either of them will completely destroy that Pentium D 960. And at the same time draw much less power.

The E6000 series will run on 200 MHz /800 MT FSB, which will cause them to clock much slower than the higher end E2000 and E4000 chips.
And E6700 might lure with 2.66 GHz, but at 200 MHz FSB it will run at 2.0 GHz, at which point a 2.6 GHz E4700, a 2.4 GHz E4600 and a 2.2 GHz E2220 will be faster in most situations.

I snatched an E4600 a couple years ago as test chip for delidding, and that thing kost me under 1€ including shipping.
All of them are available cheaply, so there is no reason to go with a Pentium D unless you really want a Pentium D for any reason.

thanks alot, that was amazing
how about e5700? this cpu is around 0.8€, and i believe it works on 945.
then i should care about picking 800FSB, since this motherboard down clock 1066 to 800.
(also the price doesn't matter since all are around 1€)
also the reason i thought maby D960 is better is because its 3.60ghz. that's all

how about the Q6600 comment? do you really think that its possible? perhaps you may say that, where did i saw that comment?
