Hi,

Here is my configuration:

I am upgrading my CPU. My options are:
- AMD Phenom II x4 945 (95W TDP, tray) 550 Kuna (~96 USD)
- AMD Phenom II x4 955BE (125W TDP, BOX) 630 Kuna (~110 USD)
- AMD Phenom II x4 965BE (125W TDP, BOX) 695 Kuna (~122 USD)

I have almost decided I will not go for a 965BE - it's the same as a 955BE but with multiplier 17 instead of 16.
That is somethenig I easily change in the bios, that is not woth extra 12$.

But my main decision problem is betveen 945 and 955BE.
945 pros/cons: lower power draw, lower heat production (my Freezer64 would cool it easier than a 125W model), lower stress on the motherboards VRM and chipset, lower stress on the PSU, lower price, ... / lower clock speed, a bit weaker memory controller, harder to overclock
955BE pros/cons: unlocked multiplier (easier to overclock), higher core clock from the start (200 MHz per core), comes with a heatsink (tah I could give to a friend of mine who has a weaker one) ... / higher stress on the VRM and others, higher price.

Why am I upgrading? My CPU bottlenecks my GPU, for example in Battlefield 3 my HD 7770 does not go over 70-80% usage whatever I do, the processor goes 100% on all three cores.
How long should the upgraded PC last for gaming etc? Let's say a year or two.
& My next upgrade (soon) will be an 120GB SSD, but that does not have the priority right now.

Which one would you choose if you were on my place?

Thanks for your time and help.

Best bang for the buck is the 955 BE, you will definitely want an unlocked multiplier for overclocking.

yeah i would say the 955BE and you artic cooling freezer 64pro should be a fine cooler for the 955BE and i would say you could even OC on the AC freezer 64pro without to much to worry about

How smart is it to overclock a PII 955BE on a 3+ year old motherboard with 4+1 cpu power phases that has been running a unlocked PII 550BE with increased voltage (TDP ~140W says CPU-Z) for about 2,5 years?
The board I have is not an 8+2 or 6+2 board, it even isn't a 4+2 board. And no digi-power. A simple plain 4+1 not-heatsinked.

Also, some people say they don't see a significant performance improvement while overclocking their 955BE/965BE. How true is that?

im not sure how smart it would be but you can always try to oc abit just try on the stock Voltage and see how far you can get it. and i can't tell you alot of the performance improvement it depends on, how high you can OC it i would say

eBay is not an option, only available in Croatia (payment method - cash).
No1 here is selling an used Phenom II x6 (for a reasonable price).

Ordered a Phenom II x4 945, 955BE became unavailable in the only store that still had it.
965BE is to expensive a upgrade for my platform.
The Phenom II 945 shoul arive tomorrow to my house, or maybe the day after.
