Intel Core 2 Extreme QX9770 Quad-Core Processor, 3.2 GHz, 12M L2 Cache, 1600MHz FSB, LGA775

excelent

Just because you've listed this CPU as retailing at $1,699 doesn't make it so. The QX9775 retailed around $1,499, and this CPU retailed (in summer of 2007 when it came out) for only $1,399. Your $1,300 discount is actually an $800 discount, and I'm not so sure that is enough for a CPU that is nearly a decade past its prime.

I helped a friend with this CPU (he went all out and spent 3k on the entire computer) about 2 years ago and he still has it to this day.This CPU is an extreme edition (meaning it has an unlocked multiplier) and can overclock very nicely for enthusiasts. This is not difficult to overclock to 4.0GHz and over on good air cooling. It's 12mb of L2 cache and wide variety of instruction sets ensures all programs run smooth and fast. This cpu will perform very well in CPU benchmarks such as Mark06 and Vantage.However, one of the problems is heat. It's TDP is already over 130w, so you need a good CPU cooler/HSF. High end overclocking demands either a high end HSF with 120mm fans, or water cooling. Furthermore, another problem is the price and timing of the release. This CPU is overpriced for the now obsolete 775 socket. The i7 920 came out 9 months after this CPU was released and outperformed it by a good margin - with less heat, better architecture, features such as hyper threading and turbo boost, etc.Furthermore, even for Core2Quads series, this CPU doesn't offer the best bang-for-your-buck. A Q9550 and Q9650 costs around $200-$300 (1/5 price), $300-$400 respectively (1/3 price) and performs almost the same. The Q9550 and Q9650 dont't have unlocked multipliers, but will still hit an overclock near 4.0GHz with good air cooling.Pros:1. Fast and top of the line Core2Quad2. unlocked multiplier for enthusiast overclockingCons:1. Expensive when it first came out, still expensive now2. Came out less than a year before i7s, which made socket 775 outdated and obsolete3. Outperformed by far cheaper i5's and i7's today.4. Loses in bang-for-your-buck to cheaper Core2Quads such as the Q95505. Produces a lot of heat > 130w TDP

First class!!!

I can buy a 5960x and almost a MSI GODLIKE GAMING CARBON Edition for that price why would anybody be that idiotic to buy a outdated socket for 1.5k?

Much too high of a price for an outdated socket type. A core quad @ 3.0 goes for around $80. The extra .2 is not worth the huge price difference. For this price an lga 1150 quad can be bought.

Yes, sell a 10 year old processor for 500 bucks. Or better yet, for 500 bucks someone could just build a new pc with a processor that would run circles around this one.
