5 out of 5 eggsFUNNY

Pros: Pro Yea 5 years ago

Cons: First off this chip can only run on a P35 M.B. I mean like 4 years since a P35 was made. And this 200 $ is more than I paid for my 2500 plus this runs on 800 Ram even W7 64 would be a waste to use on this chip with 800 ram. And these O.C. to 3.2 but with a top of the Line M.B. so 2.66 is all your going to get that is if you can Find a P35. I don't think SO.

Other Thoughts: Seriously 200$ for a Chip that has NO M.B. anywhere to be found and 800 Ram has Intel really gotten that Cheap I Guess this proves they Have.

5 out of 5 eggsWhat

Pros: Wow, I still have one of the earlier Q9450 version that is at least a year older than the originals of these Q9400 in my main gaming computer. What happened did newegg loose a whole bunch of these and just find them now. I Love these processors. They overclock well and has treated me nicely but really, if mine which is now a good 4+ years old died on me I would upgrade by now even if the price was reasonable. Still I can't express how impressed I am by newegg to actually do this, if they did it 2 years ago I might just have bought a back up one. Too bad these were built so well even after 4 years of overclocking my 2.66 to 3.5 ghz its still is not destroyed. Still while a good idea newegg, its after 4 years. I think though after 4 years, anyone reading this is probably wondering why all gamers would not have already upgraded or rather why, me who is writing this, is seriously still using one of these and has not upgraded already. I think this is great and I find it hysterical that they actually still have some core 2 quads in stock.

Cons: next cpu's lets price this more reasonably after 4 years and do what you have just done 2 years earlier.
