5 out of 5 eggsBoth are very fast

Pros: I own both the QX6850 and the QX9650, both are on good over clocking boards.The QX6850 runs hotter and does not over clock as well. Both are very fast, but the QX9650 is (without a doubt) the faster of the two. The smaller dye size (Manufacturing Tech) and a newer-better architecture gives the QX9650 a clear advantage.

Cons: Buy a good CPU cooler.

Other Thoughts: The Manufacturing Tech size difference is a big deal, The smaller dye sizes run on less voltage, and will produce less heat at identical clocks. The heat jump during use at higher clocks is also not as drastic.

5 out of 5 eggsSuper Fast Like A Formula One Race Car

Pros: The QX6850 is the fastest Intel Core 2 Extreme Quad Core Processor with the 65 nm Manufacturing Technology Process.
It is comparable to the newer 45 nm Processor QX9650, as both have 3.0GHz clock speeds with 1333MHz FSB's,
the only diference is the QX6850 has only an 8MB-(2x4MB) L2 Cache versus 12MB for QX9650.

I have been using mine since August, 2007 and could not be any happier when it comes to overall performance, either one you will not go wrong or be disappointed !!

Sorry Newegg but since then I have purchased and any future Purchases will be from Newegg #1 E-Tailer, You have lifetime Customer, Tahnks for your exemplary Service !!!

Cons: Unfortunatly I did not purchase this from Newegg in August 2007

5 out of 5 eggsUpdate on the beast

Pros: Sweet! very excited finally got it to run stable at 4.0!!! took a lot of resets and blue screens but the remedy was VOLTAGE! This is my first time really doing a lot of over clocking and now i know. CPUs love voltage. Running 1.6V at 333x12. unlocked multiplier is handy, probably could get lot higher on more extreme board. I am running on EVGA 750i . If you can afford DDR3 get the Striker boards or the new EVGA 790i Digital PWM, got all solid capacitors, should push some good numbers and is good idea if you want to do extreme overclocking.

Cons: nope

Other Thoughts: QX6850 @ 4.0Ghz!

If you have this thing make sure you overclock. 3.6 is no problem just max green voltage and change multiplier to 11. Anything higher than 3.6 requires more tweaking. Ran 1266 FSB with 13 multiplier for 3.8 which required nearly no voltage increase and 100% stable.

Oh and give your CPU 8Gb of ram!

5 out of 5 eggsVery Fast, Works like a Charm

Pros: Very fast CPU, especially after some good overclocking. Installed easily on my MSI P6N motherboard and booted with stock speeds without a problem. I am using an air cooler, the Xigmatek S1283, with a 120mm fan in my Antec P182 case. I overclocked to 3.4GHz and run about 35-40C on idle and up to about 65C on load. This thing can easily take the heat and you really should not start worrying about it until it gets over 75C. Makes everything you do so quick and simple. Opening Photoshop was sped up by at least 3 seconds, unzipping large documents is nearly instant, Xvid encodes at about 75-90 frames per second, it is amazing. For those wondering, this scores a 5.9 (the highest rating) on Windows Vista Experience Index, and therefor overclocking gets a 5.9 as well. Pretty amazing stuff. Stock heatsink is not good enough, I would not even try to use it. If nothing else, get the nice cheap Freezer 7 Pro.

Cons: None at all. I would not pay retail price for it, but if you can get it through something like Intel's Retail Edge, go for it!

Other Thoughts: Intel Core 2 Quad Extreme QX6850 @ 3.4GHz, Xigmatek S1283 CPU Heatsink, 8GB DDR2 RAM, MSI P6N SLi mobo, nVidia 9600 GSO, Antec P182 Case

5 out of 5 eggsSuper Fast Processor

Pros: Wow this thing is fast. Easy to overclock, couldn't get as high as i hoped though. Running it at 3.8Ghz :) I got a Zalman 9700 CPU fan and a Antec Twelve Hundred case, and i idle at 45c, and 61c under load, at 3.8 :)

Cons: Price of course. I was able to get it through a special promotion and saved big bucks so it was worth it for me, and now that the 45nm are nearly same price not much point in getting this one anymore. Wanted to hit 4.0 but couldn't get it. Make sure you flash bios with latest update if your multiplier is locked, my EVGA 750i out of the box was locked at 9.

Other Thoughts: Its Fast. For most people I would recommend the 45nm quad cores with 12mb cache, unless u want unlocked, still go 45 though.

QX6850, Zalman 7900, EVGA 750i , 8Gb OCZ Platinum 1066, Antec 1000w, 9800 GX2, Raptor x(need to upgrade to veloci), Soundblaster X-Fi Titanium Sound Card(looks cool)

5 out of 5 eggsGreat CPU

Pros: Fantastic stock speeds, super powerful heavy-duty heatsink fan

Cons: price

Other Thoughts: There is no need to invest in an after-market heatsink fan because the one in the box is excellent. After purchasing CPUs at or under $200 for 10 years, it is mind boggling to have a $1000 CPU. It is well worth the money. Add a 10K rpm HD, a mobo and memory to get it to 1600 FSB, and 280 nvidia video card, and you will still spend less than 2K on a super machine.

5 out of 5 eggsExcellent Processor

Pros: The QX6850 running at stock speeds is very capable of handling everything i have thrown at it. I will routinely have multiple windows open, multiple apps, and still am able to instantly open up anything else (including games), without hesitation. Also i upgraded from a Q6600, i didnt think i'd see very much of a difference in speed, but i was totally blown away.

Cons: The only con of course is the price, simply because its 65nm but still retains the 1000+ price.

Other Thoughts: If you have the need or ability to see the benefit in quad-core processing i would definitely recommend this product. It runs much cooler than my Q6600 did (both are stock speeds), and will run circles around anything i throw at it.

5 out of 5 eggsPerfect

Pros: Works great with FSX & pretty much any program or game that's maily processor dependant in terms of FPS. Works smoothly with my other hardware, didn't even need to update bios. Stable and runs cool with my zalman 9500 ambient air cooler.

Cons: None at all, perhaps price, but intel offered a sweet deal through their retailedge program... nabbed the processor for hardly anything.

Other Thoughts: Installed on an ASUS P5N32-eSLI mobo, 4GB PC5300 G.Skill, 8800 GT x2 (sli), WD Raptor 150GB, WD 500GB, QX6850 /w zalman 9500, arranged in an Antec 900 mid case.

5 out of 5 eggsFantastic Proc

Pros: Unlocked multiplier, 1333 FSB. This thing tears through any video encoding I throw at it. I did manage to finally pin it at 100% usage, using 19 simultaneous Premiere CS3 encondings. Being a professional system builder I did get this proc for about 1/4 of retail, but it is worth far more than what I paid. It runs at 38 C with a Zalman 9700.

Cons: Runs a little warm compared to the 45 nm procs. Price is a little high if paying retail.
