Which CPU should I choose?

[htredneck]

I could use a little help choosing a new CPU. I will buy it in the next few weeks. With my hardware which would go well (Cost/performance)?

Thanks

I think the Asus P5B will support the new FSB 1333 CPUs if you update the BIOS. Check with their Support people. If they say yes then get an E6850, otherwise I'd pick an E6600 or E6700.

Correct me if I am wrong but isn’t Prescott a socket 478 ? If so, I wouldn’t bother upgrading the CPU, you need a new Motherboard so you can get a decent CPU…

Good question. Yeah, what kind of P5B are we talking about? The models I found here:

http://ca.asus.com/search.aspx?searchitem=1&searchkey=P5B

support Core 2 Duo, and some even support quads. A Q6600 may be even better for you than an E6850, depending on what you're planning to use the PC for.

If you change the mobo I'd recommend a GA-P35-DS3R:

prescott is lga 775 not 478

prescott is lga 775 not 478

It's actually on both socket formats.

prescott is lga 775 not 478

"Corsair 800" indicates LGA 775.

I tried to update my signature with a few more details but I haven´t figured it out yet with the new form.

Asus P5B (Vanilla)

The Prescott processor and Gigabyte heat sink are the only things that haven´t been upgraded from a system I built 2 years ago. The board I bought not too long ago because it was cheap and stable. I can wait a year until the newer and better boards have the bugs worked out (and I have more money). I can´t wait any longer for a new processor. I updated the BIOS yesterday.

Here is some more info from Everest:

aevm already posted the right answer. Unless Asus tech says that the board, with BIOS update, will support Q6600. At $266 after price cut (lot price I think), it's so cheap you might want to consider it. The additional cores won't be fully utilized in most apps for a while, but the software guys are working hard toward that end, so it won't be too long.
