AMD 945 vs AMD 955 be

How much would the performance be between this two cpu?
I know AMD 955 BE is better but i have a tigh budget. Also , i plan over clocking.

Here is AMD 945 with a mobo:

This is a oem cpu so i will get a cooler.

Here is AMD 955 with a mobo:

Looking at price difference it is $193.04( AMD 945 combo after bcb) vs $229(AMD 955)

Please suggest!
Thank you in advance

  1. Go with the 955 since you plan on OCing, simple because it is a BE processor which means for much easier OCing, which will be a major time saver and will increase stability in your overclocks.
  2. BTW the oem version is way to expensive, find the non oem version if you do buy the 945 and use the difference to buy a quality heatsink!
  3. The difference on stock is only the 0.2Ghz clock speed, but with the 955 you'll get a higher OC.
    The limit of the 945 is usually around 3.6Ghz on air, while you could go up to 4.0Ghz on a 955 with good cooling.

    Though If you're on a tight budget, you can also consider a AX4 635/640, the 640 OCs just as well as a 945, with the 635 not much far behind. They're just missing the L3 cache, which unless yore doing heavy encoding, is not going to help much on performance.

    Are you sure Amdx4 640 comes in par with Phenom 945.
  5. ^ Pretty much, the extra L3 cache is nice but not necessary. One major advantage that the 640 has over the phenom is that the Athlon archeticture is known to run much cooler and tends to be more energy efficient, even though the phenom and the athlon in this comparison have the same wattage rating.
  6. the l3 cache also helps a bit in games though. On average about a 10% higher minimum frame rate. Not too much but still something.

    Read this is you what to see a clock for clock comparison between Athlon II and Phenom II, aka the difference the L3 cache makes.
