[Solved] AMD 955 or AMD 9950?

Hi everyone,
I'm going to buy a new computer soon, and in the moment I have two choices in processors:
1. AMD Phenom II X4 955, socket 3, 3.2GHz http://products.amd.com/en-us/Desk [...] spx?id=532 for 670€ (1006$)
2. AMD Phenom X4 9950, socket 2, 2.6GHz: http://products.amd.com/en-us/Desk [...] spx?id=476 for 550€ (826$)
(these are the prices of whole configuration, the only difference is CPU)

My questions are: Which one is better for its price?
Are their differences in performance really worth paying 120€ (180$) more?

I really need your professional opinion. I'm buying it on thursday, so please help ASAP!

Appreciate any kind of help..

Sorry when I re-read your post it said the total configuration price.Never mind

I would say it's not worth the price, at least not that large of a price difference. I've got both a Phenom and a Phenom II, I can without a doubt say the Phenom II is a better processor, but not $180 better.

Are the prices really that different? In the US, you can get a phenom II 955 for just ~$180.

In agreement with everyone else, the price probably isn't worth the extra performance, but you should check out the athlon II quad core, which would probably beat the phenom 9950 by a little bit, and it would also OC better if that's your thing.

Sorry, my bad. I didn't knew that the motherboards in both configurations are gonna be different, I wasn't informed about that (my friend made those offers for me). So the motherboard thats in conf. with AMD 955 costs more than that in 9950.
Again sorry, my bad..

So i've bought a computer 3 weeks ago, and configuration is:
Motherboard: Asus M4A785TD-V EVO (has integrated graphic card, can work in Crossfire)
CPU: AMD Phenom II 945, x4, 3.0GHz
RAM: 4Gb
HDD: 1Tb
Graphic card: ATI Radeon HD 4800 (with 512Mb DDR5)
and
Windows 7 64-bit

all that for 610€

I know, I haven't. I see those computers at supermarket with SUPER PRICES! I spit on them.. xD
Me and my bestman have solved a a configuration like puzzle..

Tnx man
