AMD Athlon 64 X2 7750 Kuma

Right now I declare this king of budget overclocking!

The reason I say that is this is a REALLY good CPU for the money and one I plan to get. From what I can tell these were Phenom x4s that had two cores disabled via laser during fab due to defects in those cores. There is nothing wrong with this as they are working with a small process and there is going to be bad cores. They aren't going to suddenly give you errors on the remaining cores as the controller knows those cores are dead.

So you get all the features of those super expensive x4 black editions at a cheapo x2 price (of course with only 2 cores instead of 4) Also the reports I am reading say it is a good overclocker up to 3.2 due to less heat (2 instead of 4 cores means less heat)

Heh with this advertisement I ought to be hired by AMD :P

Anyway just wanted to let the folks know about this one. It will likely be the best offer for a few years because the 45nm Athlons of the future seem to not have any L3

Just a note it seems the 7750 is almost as good in games as the x3!

And the difference is really small!

Basically in my view this means you can build a 3-4 hundred dollar computer now with 2 sticks of nice DDR2 memory. And it will run overclock and run windows Vista fine! Then around late October you do an MLU on it by adding another 2 sticks of Ram maybe a video card to crossfire/SLI with and of course the main event! Purchasing Windows 7!

After that MLU you can do another next year if AMD gets a REALLY good 45nm AM2+ dual or tri core at 90-100 USD.

However keep in mind the huge costs of dev these days. Crysis was a huge investment for EA and look at them these days Far Cry 2 was a huge investment for Ubisoft and look at them!

My computer has an Pent 4 HT at 3.2 Ghz. It is old (One of their first 90nm CPUs) and with upgrades over the years (1.5 Gb of ram now and a Nvidia 8600 GT) It runs Silent Hunter 4 with the settings turned up at a great FPS.

Unless Ubisoft plans to spend about as much money on Far Cry 2 on Silent Hunter 5. Such a build based on the 7750 is going to last you heck 2-3 years with a few MLUs. And by that point either 32nm will be king or 3D transistors/quantum parts will mean a change to the face of computing.

It is interesting what they do with cores these days. I can say that multiple cores are great if you open several programs at the same time. Unganged RAM usage by AMD is a nice feature where it dedicates a stick of RAM per core. I did add another 4 gig of RAM to my computer for a total of 8. I can say I do not see a substantial increase in performance over just 4 gigs that I was running in single channel. But hey, it is there if needed. Having the ability to overclock your cores is a great feature for keeping a computer for a long time.

Indeed!

After reading alot it seems that if you have a REALLY good air cooler you can drag this thing up to 3.4

Sound like something you would get a typhoon for.

And more cores are great for modern games that are starting to effectively use them. but games still rely more on speed rather than cores. So overclocking this to 3.2 is far better than sitting on a cheapo 2.1 x4.

Well, AMD had the forethought to make their cores a overclockers dream. The Black Editions allow that and can clock quite a bit with just air cooling. My 7850 from reading overclocking test, etc. can reach 3.0 stable and cooled just by air. The Intel cores can overclock also. Most seem to like the Intel. Everyone has their favorites I guess. Personally, I do not see myself fooling with overclocking. My luck it will all go up in smoke

If one's core is at 65nm it is easier to overclock compared to 90nm which will get REALLY hot at the slightest change in voltage.

However unless it is a black edition I strongly advise against any overclocking unless one is very knowledgeable.
