Ok guys I'm intending to upgrade my e2220, I can either get the e7400 off newegg for $117 or try to get an E6600 for around ~$70.

Stock speeds aside (I can overclock) the E6660 would be faster at the same clock speed than the e7400 correct?

Which would you buy, and also, is ebay a reliable place to buy computer hardware or are there a bunch of scammers selling dead CPU's?

More about : e6660 e7400

Wow, I really thought I would have got a reply by now.

EBAY is a great place for used CPUs.
The vast majority of people there are legit sellers, but paypal will reimburse your money if you do get scammed. Even buying new items from retail/online stores carries its own risk such as DOAs.

IIRC, there was someone around here who was trying to sell his E7400.

Also, E7400 > E6600

I know stock it is but what if they were running at the same ghz level, then wouldn't the extra meg of cache on the e6600 beat the e7400?

E7400 is wolfdale based and is faster.

No, as someone mentioned, the E7400 is a 45nm Wolfdale chip and the E6600 is a 65nm Conroe chip. The Wolfdale chip is newer architecture and is faster clock-per-clock, outweighing the benefits of extra cache. The Wolfdale chip also overclocks better and runs cooler.

If you're on a budget, you might want to look into the Pentium Dual Core E 6000 series chips; the L2 cache is 2 mb (vs. the 3 mb of the E 7000 series) yet both have a 1066 MHz FSB and are based on the Wolfdale core.

Just got lucky and found a Q6600 (G0) CPU on Craigslist for $50.00, got that beast running 3.6 on Xiggy air-cooling.

Maybe try Craigslist first and get lucky like me!

Thanks for all the replys, my mom is in a finical bind so I must "loan" her money so no e7400 for me.

However I can upgrade a very crucial component.... my ram, it's been stuck at 1.5gb ever since I got this mobo. One of the sticks is even faulty and does not want to run at the correct speed or overclock more than a few mhz.

I plan on replacing it with quality ram and overclocking the *** out of my E2220 hopefully to 3.5GHz+ which should hold me over until I can get a new cpu.

I have the e7400 and its a great cpu. I upgraded it from a e4600 and it is alot more efficient. It is a tad bit faster as you will notice for some applications and the startup that yopur pc will start a bit quicker. It is 2.88ghz so if you have a good motherboard and cooling you can overclock it to 3.4ghz safely or even more.

It is a low powered cpu and im running it with a 550watt 80plus psu along with a new 5850 and 4 gigs of RAM, 2HDD's, and a gigabyte cpu cooler. I would only recommend the e7500 just because it may only be $10 or more if available.

Actually, I have never heard of the E6660 cpu, but I guess it is dual core, its better that you get a core 2 duo of the core brand. In my case it wasnt so I just got the e7400. It is a great CPU, dont even think of saving because in the long run, you will not likethe e6660.

^ He's probably talking about the E6600, the 65nm Conroe from the original Core2Duo lineup.

He can actually get a E5x00 PentiumDual Core series, which would still be very good. It has less cache, but it's newer architecture and 45nm Wolfdale Core makes it run just as fast if not faster than 65nm Conroes.

+1 for new ram and trying the overclock.
