AMD Athlon 64 X2 4400+ - Athlon 64 X2 Toledo Dual-Core 2.2 GHz Socket 939 Processor - ADA4400CDBOX

Pros: This Processor can and will take anything you throw at it. If you're someone who likes to multitask and do several things at once, buy this processor! I've been able to defrag 2 hard drives(not recommended while doing other things), burn a dvd, encode an MP3 and play Quake 4 at the same time without any kind of slow down.

Cons: Price, although I think it's the best bang for your buck.

Overall Review: You may see issues with older applications not behaving correctly. I encountered a problem within Half Life 1 and its mods(Counterstrike, DOD) where every few seconds I would stutter and the more USB devices I had plugged in, the worse it go. After 3 days of pulling my hair out, I come to find out that the application couldn't handle the dual core. You can define the amount of use with a given application by going into Task Manager(CTRL-ALT-DEL) > Processes Tab > Right Click Executable for Process > Choose set Affinity and then you can choose which processor to use. If this is an application you use frequently, I'd recommend downloading Powerstrip 3.61. You can setup a profile in there so that everytime a certain application is launched, it only runs it on the first CPU. Hope this little bit of info helps some poor soul from the agony I went through.

Pros: An excellent processor, works quite well with Linux in both 64bit and 32bit flavors, as well as Windows XP in both 64bit and 32bit flavors. Extremely fast, and has a 1MB L2 cache for each logical processor.

Cons: Have had some issues with the Toledo core processors so far. One processor installed correctly, was left to "burn in" over the course of a couple days. During that time, the computer had shutdown and then refused to boot. Switched out processors with another 4400+ Toledo, and the computer booted. Sent the faulty proc to AMD, who said they had no idea what was wrong with it, but quickly sent a replacement, which worked fine.

Overall Review: This processor is excellent for multitasking performance. Be aware that it does not perform as well as a single core processor doing a single job, however. An example is games (currently), which are not usually multi-threaded and are capable of utilizing only one core at a time. This will change over time, especially since Microsoft has announced a commitment to 64bit processing (meaning more 64bit processors will be sold, and multi-cores will be more common). Expect the usefulness of the processor to increase over time, as applications are developed to take advantage of the technology.

Pros: This processor is extremely fast no real artifacts and no problems from the outset. Newegg got the product there promply as always. Installation was easy with the information shipped with the processor.

Cons: Windows does not properly handle all of the features of this chip yet. See microsoft tech article 896256. This resulted in reduced performance which was correctable by installing the hotfix which was provided by Microsoft following significant prodding.

Overall Review: Overall great processor minor technical problems for a new peice of hardware.

Pros: 939 pin supported by many motherboards, Dual Core Processor, Multi-tasking is now a reality.

Cons: Shipping by UPS

Overall Review: UPS Shipping is horrible! Ordered on Sunday before Turkey day on the 3 day free UPS and I didn't recieve it until 7pm Monday after T-day, 8 days total, since UPS didn't ship on Friday or Sat while Fed-Ex trucks were rolling past my house. Then the box had a huge punctured hole. When questioned about the hole, I was told "so, what do you what me to do about it?" Luckily no damage to the CPU. I'll never use UPS again!

Pros: Runs cool, Overclocks decently, OCed mine to 2.5GHz right out of the box. Good price. Comes with heatpipe cooler.

Cons: AMD is no longer manufacturing them, or any X2's with 1meg L2 Cache. Heatpipe cooler doesn't have a very smooth base.

Overall Review: This processor replaced a single core Opteron 146@2.8GHz. As I startred doing more and more multi-tasking as well as video capture/encoding I realized that I could really benifit from a dual core setup. Didn't want to spend the $$$ on C2D, board and new DDR2 ram so this was the most logical upgrade. My encoding time has been nearly cut in half and gaming is as flawless as it always has been. I'm really enjoying the dual core experience sofar.

Pros: This thing is blazing fast.I have music, system mechanic and a temperature monitering program all while playing cod2 with everything on high with no lag what so ever. Same with bF2. Stock HSF is not as bad as ones that come with other processors. It has copper heat pipes and an 80mm fan on it. Keeps temps low.30C idle 42C load. 2 X 1Mb L2 cache is nice. Allows for super fast processing. Blows everything Intel has out of the water other than conroe of course but who is gonna buy that right now its prolly gonna be like a million dollars. This will do just fine for anything that you could possibly want to do.

Cons: For some reason beyond my recolection AMD forgot to include cons with this processor.lol

Overall Review: If you want a trooper of a processor and dont want to spend that much this is for you.. but you have to get it now because for some reason AMD was like "Hey lets discontinue pretty much all of our socket 939 processors and push AM2." The only difference is one pin and to see any performance increase which is minimal at that you have to use DDR2 which is still kind of expensive. Right now its not worth it, but when the prices drop then you might consider AM@. Right now 939 is your best option. I really think that AMD is shooting themselves in the foot by eliminating all socket 939s seriously why would you want to get rid of the FX-60 right now? Yeah it's beyond me too.

Pros: Multitasking gallore, it handle's everything you throw at it just fine!!!

Cons: none!

Overall Review: Since most applications/games dont support X2 chips fully yet, you need to do the little trick with disabling one of the cores for the application. For example, in BF2 i was getting weird stuttering eventho i was getting well over 80+ fps with everything on HIGH with my x1900xtx. The fix: ALT + TAB, then CTRL + ALT + DEL, and then find, BF2.exe .......right click, set affinity, uncheck CPU 1 and the stuttering is gone and the applications works flawlessly!! cheers!

Pros: WOW, is all i can say. I think the price/speed ratio is great with this cpu.

Cons: Im not sure it has any but if i were to pick one it would be a better aftermarket cpu cooler even though the retail package cpu cooler is fine.

Overall Review: I have yet to overload this thing even when it said 100% cpu usage, its almost scary to think what will bog this cpu down because i just cant do it. I have had mcafee antivirus doing a scan, tmpgenc converting a video, chatting on ventrilo, all while flying a jet in battlefield 2 with a 25ping and Zero system lag.
