I ALREADY KNOW THAT THE 975 IS BETTER. But could someone explain in detail why its better? Im looking at the specs on newegg.com and the only big difference I see is that the Intel has 6mb L3 cache more. I know that the Intel has a lower clock multiplier...

Nehalem (core i series) is better by architecture.. Though, one can't directly point out the i7 975 to be better compared to the X4 965.. It is overall a faster processor and sits on a more feature rich and complete platform but, there are several other factors that come into play when deciding between any two choices..

Price. Many of us are limited by our budgets, so we look for the best deals we can find on parts that we know will perform adequately. Yes, the i7 CPU is faster. It also is more expensive and the motherboards and triple channell memory are more expensive than AMD as well.
I can't think of a single game or other software that the X4 965 isn't capable of handling. Provided you pair it with a decent video card, it should play anything.

You can check the reviews of both and you can learn more about their architectures,design and features

AMD obviously has the price advantage.. But the bigger factor is the price to performance figure.. In the most adverse situation, the X4 965 would give 70% of the i7 975's performance at 20% of its price.. Who can overlook this.!! The performance difference is even more narrower when it comes to gaming..

^^Quite similar user name's wont you say?? 
The i7 975 is way better. Comparison is a bit difficult when you know that they are completely different generations of processors. It would be better you can compare with Quad Q9550 with the X4 965. They are much more on the same lines and same generation of quads.
Before you delve into comparisons, read a bit about the the links Maziar gave and also this. This would give you an idea why the new Intel architecture is awesome!

Two Maziars in one thread! 
A few things actually.
The Intel Core i7 975 has 1 MB L2 cache and 8 MB of shared L3 cache, while the AMD Phenom II X4 965 has 2 MB of L2 cache and 6 MB of shared L3 cache. Intel's CPU has the higher clock multiplier, although the AMD's has a higher clock speed.
If you're wondering why...
The Intel Core i7 975 has a base clock of 133 MHz, and a multiplier of 25. 133 x 25 = 3,325.
The AMD Phenom II X4 965 has a reference clock (AMD's base clock) of 200 MHz, and a multiplier of 17. 200 x 17 = 3,400.
Their different architectures work differently.
As said above by others, the i7 975 platform is considerably more expensive. If you're willing to spend $999 on a processor, might as well be the i7 980X. Otherwise the Phenom II X4 965 BE only costs around $180 in comparison, less than a fifth of the price. High end 890FX motherboards costs around $200, while higher end X58 boards cost more than $300 normally, although there are quite a few entry level X58 boards which cost around $200 as well.

Only the i7 980x and i7 970 from the i7 lineup use 32nm. All other i7's use 45nm process. And only the 980x & 970 from the i7's use Turbo Boost.
As for the question, first of all the architecture of the i7 CPU is much better. They have +2MB L3 cache, Quick Path Interference (opposite of AMD's Hyper transport and better), Hyper Threading, Tripple Chanel DDR3 etc.
But the X58 platform also costs more than the AM3 platform, mainly 'cause of the mobos and the tripple channel DDR3 RAM.
So, if you're on a budget, and mainly gaming you'll want to get the X4 955/965 with a nice 880/890GX/790GX/FX mobo, or the i5-760 CPU, which is cheaper than the i7 and is sometimes faster than the PII X4's. If you want more performance and have a bigger budget, the i7-930 is the way to go.

Well "Maziar" is a common name in Iran
I forgot to post another link, here is more info about AMD Phenom(and II) architecture

Akuze :
The X4 965 matches a i3 540 ) http://www.anandtech.com/bench/Product/102?vs=143

LOL wut??? That's not true at all. It matches the i5-750. And you can see that this is a beta app.

rohn_avni :
i think i clearly wrote the i7 975 ......................why r u telling abt other processors here???
I listed other CPU 'cause if the OP is considering one of the two CPU's to buy, he should know they are not worth the money, especially the i7-975. Why would you buy the X4 965 when the X4 955 is almost matching it's performance? They both OC great, so you got no reason to buy the X4 965. Same case with i7-930 vs i7-975.
i7-970 & 980x are six core CPU's and have turbo boost and use 32nm tech, i7 920/930/940/950/960/965/975 are quad cores and use 45nm tech and don't have turbo boost.

if your a real person like most of the entusiest world you have a limited amount of money. while the 975 is a faster processor you have the fact that it costs about a grand to purchase it. you can now buy the AMD 965 for about $180(less than twenty percent of the price.) while the gerneral question is which one is faster yes it is the newer and more advanced 975 but that being said if your buying these to game with on amazing air or liquid cooling you can clock the 975 to 5.0Ghz where as the 965 can clock out on air at 4Ghz stable whitch is nothing to scoff at compaired to the i7 920 (more compairable to the 965 in the era of technology) which tops out at about 3.8Ghz stable OC.
unless this is strictly to crunch data your better off buying a 965 and OCing it to edge up your performance and then spending $600 of the money you saved on a 5970 video card and stick that extra $200 in your pocket.

But could someone explain in detail why its better?
If this is what he is asking, why is no one talking about the IPC of the icore models vs the IPC of the phenom II models?
