I would like to get a new 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?

ASUS web site says that my board can use either a Core 2 Duo or a Pentium Dual Core provided they run at no more than 1066.

The CPUs mentioned above are specifically mentioned as being compatible.

I presently have a 1.80 GHz E4300 Core 2 Duo that I can sell. Would the above CPUs be significantly faster?

For my understanding, could you tell me if a Core 2 Duo is faster than Pentium Dual Core if both CPUs run at the same speed?

You would see a benefit jumping from 1.80GHz to 2.93GHz, no doubt, even if you are just doing basic stuff its still noticeable, and a decent increase for gaming or video editing.

The main difference between the two chips i linked is the 2MB vs the 3Mb cache. There is a benefit of having a higher cache but I dont know exactly unless you are doing bench marks or recoding video and watching time remaining how you would tell the difference between chips that are that close.
So technically yes. But I cant say really that there is a HUGE difference between two chips where the difference is 1MB of L2 cache.

OC your E4300 to 2.4 GHz with 1066MHz FSB.

Totally agree with paranoidmage. Those e4x00 were really good ones. I own e4700 oced to 3.46ghz and I'm very satisfied. Your e4300@2.4ghz will give you a huge boost in every single task and you will not spare even a buck.
Edit: I just checked your motherboard. It does support cpus up to fsb of 1066mhz but it doesnt mean it won't go higher. This is a 965 chipset, it overclocks really well and yours e4300 if put on 3ghz or more will be really good. For a couple of bucks you can buy an aftermarket cooler and have fun with OC. You really do not need a new cpu.

I have done some tests myself with a e6600 vs e5200 on same test platform useing a Gigabyte 965P DS3 Rev 3.3 board and a evga 260GTX (192sp)clocked at 756/1512/1270 and both cpu at top stable speed for vantage

the e6600 @ 3.5Ghz with a fsb in the 1400Mhz+ range ..= 13,018

the e5200 @ 3.87Ghz with a fsb of 1240Mhz =13,115

So the 45nm Wolfdale is much better then your Core 2 as L2 Cache really never made a diffrents for the e6600 which is a far more powerful chip then your e4300 is
and cost me over $200 when i bought it new..

This is a $66.99 chip ..http://service.futuremark.com/resultComparison.action?c...

the e6600 @ 3.5Ghz with a fsb in the 1400Mhz+ range ..= 13,018

the e5200 @ 3.87Ghz with a fsb of 1240Mhz =13,115

Which helps point out that yes you will se a difference going from 1.8 to 2.93


so now the question is, are you looking for the best chip for under $100 or the best chip for overclocking for under $100. If it is the latter, disregard my first statement and listen to these guys, if you are not overclocking I stand by my answers.

Hi guys,i have e7500 clocked at 2.93 ghz,if i overclock it,what speed will i achieve without having to change the stock cooler?

I do not want to overclock. I prefer to spend a bit more money and not bother with overclocking.

Then the E6500 is your "price is right" chip.



And shayan764, from the looking I've done you can get it to 3.4GHz on stock.
If you are looking for help on how go check out the overclocking section, got some good stickies there.
Or use google for an "E7500 Overclocking Guide"
