AMD Athlon 64 X2 4200+ - Athlon 64 X2 Brisbane Dual-Core 2.2 GHz Socket AM2 65W Processor - ADO4200DOBOX

Pros: Fast, great over-clocker with an after-market fan, Cheap,65nm.

Cons: None really.

Overall Review: Idles at 25C on air with an arctic cooler 64 pro, and 30C OC'd to 2.97GHZ (11.0*270mhz). I am using it for a gaming server and could not be happier, just make sure that you pair it with fast ram to get the most out of it.

Pros: It runs about as fast as my Pentium D 2.8GHz. 100% load on stock heatsink runs at about 46C. About 15C cooler then my Pentium D. I would say as far as performance, they r very close. Heatsink was easy to put on. I'm glad they finally go a latch instead of shoving it down using a screw driver. Haven't overclocked it.

Cons: I think the best bang now is 4400.

Overall Review: Newegg sent me an open retail box. They were fast to deliver another one out overnight free shipping. I have to give them big kudos for that. I don't think there is anyone out there, except Amazonn that will do such a thing. Amazing service.

Pros: cheap, fast and quiet with the standard heatsink and fan comes with the package, my system was so quiet, sometimes when the monitor is off, I counldn't really tell if the power is on or not. I was able to overclock this cpu to 3.02ghz (11x 275) with the standard heatsink and fan,very stable. idle temp around 40c. that's a big plus,because you don't need to spend extra money to buy a better cpu fans if you need overclock.

Cons: I bought it couple weeks ago, and it cost me $65, I wish I could wait for 2 more weeks, as the price now dropped to $60.

Pros: Followed the enclosed directions for mounting the CPU and the fan that came with it. No problems. System worked first time and everytime since. Exactly what I wanted.

Cons: None

Overall Review: Not overclocking and don't intend to. Don't need to for my usage pattern.

Pros: This is my first 64 bit CPU and I'm quite impressed with it, even in 32 bit mode. Very quick, very stable, great performance.

Cons: None so far.

Overall Review: I'll resubmit my review in a few weeks, once I get this system upgraded to a 64 bit OS.

Pros: good speed, descent overclocking ability, the heatsink/fan are descent enough to get it clocked to about 2.4ghz without any problems.

Cons: none for the price, but 1MB L2 cache would be the next step up.

Pros: This processor is really fast! Running with an Asus mobo and 2 gig of Corsair memory and Vista 32 OS. No heat problem that others have said they had. You will love the lever on the heatsink/fan. It makes it so much easier than the old socket A. Don't let the price fool you, this is not a budget processor. This will run just about everything you throw at it. If you are upgrading don't think twice, buy it.

Cons: None

Overall Review: Keep in mind on the newer processors and mobos the power supply is very important. Make sure your power supply is able to handle it. I feel that at least 450 watts is needed to run this and a decent mobo with a midrange video card. With that said go out and order it and have a great computer for the next 3 yrs.

Pros: Lots of overclocking headroom, can even reach decent clocks using the stock heatsink\fan. Very impressive chip for so cheap. The 3GHz range is a cakewalk with good cooling and half decent memory. Actually, this is still a good gaming chip unless you want to play Crysis--still can be done since the GPU is most important regardless, but I doubt you'll be looking in this price range if your wanting to play Crysis so this is probably a moot point.

Cons: Not the best performance? (obviously not nearly as much $$ either) Does run a little hot but remember that it is a much more voltage and heat tolerant chip than most... No real qualms for the price. Look at all of the X2 in this range to really decide what one is the best bang since prices constantly shift.

Overall Review: Please AMD reach this level again! (K7\K8 glory days in general) Sorry AMD, I finally caved and bought a Q6600--great chip for under 200. (I also own a Phenom 9500 which replaced this X2 because I couldn't resist the Phenom at 85 bucks.)
