I would like to get a CPU for my ASUS P5B-Plus motherboard.

It is a LGA775 board with a maximum FSB of 1066.

What would be the best under $100 CPU for that board?

What type of CPU are you upgrading from? Depending on the CPU you already have it may not be worthwhile.

I have a Core 2 Duo E4300 that I have the opportunity to sell for $50.

That will be a pretty inexpensive upgrade.

I hate to go outside of your requirements but the Gigabyte UD3R or P P45 is probably the best quad overclocking mobo out there, not to mention a dualie.

They range from 114$ to 134$?

If you're bent on upgrading, there are some cheap options, dual core type.

The E7XXX series is one....1066 FSB, 3MB cache, does have virtualization tech built in---as long as you get the E7600 that is. Cost is just over $100.

The E6XXX dual core Pentium series is another option. Less costly than the E7xxx series, only has 2MB cache, can support virtualization with the E6300/E6500 cpus. The E6300 can be obtained for around $80, the E6500 for a tad more. I built a little system with an MSI G31 chipset mb with the E6300 and even with that rather simplistic motherboard, the cpu did OC quite well, hitting 3.4GHz on stock cooling without doing any more than adjusting the FSB in the BIOS. Ran smooth---rather nice cheap cpu.

Both the above lines are built on the Wolfdale cpu.....both are 45nm tech, 65W power.

Sorry to threadjack, could i ask what ram you were running with that E6300? I've got an E6300 on a UD3L that i can't seem to get past 2.8...

It was just some generic stuff I got at MicroCenter. 2GB, 2 x 1GB sticks, that MC sells as their house brand. It was rated at DDR2 800, but was an unknown brand.

Here's a link to what I bought....although I did get it for $14/stick.

Now, as for the OC on the cpu, it didn't run exactly ultra cool, give it had the stock cooler on it, but it ran video, a simple game, Office apps all without problems. It's now gone to my father-in-law as his Christmas present. E6300 on an MSI G31 motherboard, 2GB DDR2 memory, 500GB hd, 22X dvd-rw, Win 7 Pro. Ran very, very well and is a great upgrade from his old socket 754 Athlon system he's currently using.

The e5400 (800 fsb) I have has a 13.5 multi and overclocks like a champ. It has vitualization also. 80 bucks or so.

This. My E5400 runs nice and stable at 1066 with 1.375V . . . 266 x 13.5 = 3.6GHz. Full load temps in the mid 40's C (Arctic Cooling Freezer Pro).

Edit: Maybe I should look at dropping my core volts if you're managing that at 1.26 0_o
