In laymans terms the clock speed means very little. Each model of CPU (i3/5/7, phenom II/Athlon II, core 2, etc) will be able to execute more commands per cycle (the IPC mindless was talking about). So if a computer is able to execute 2 commands per cycle and another is able to execute 1 per cycle for example, the first at 1GHz and the second at 2GHz, they will both execute the same number of commands in the same amount of time.
When AMD first came out with their Athlon 64s they were superior to anything Intel had to offer but even though their 2.6GHz Athlon 64 outperformed the 4GHz pentium 4, people just saw 4GHz. when you see 3200+ behind those older AMDs, it's their rating of how it would perform vs P4. The 2.0GHz 3200+ would perform the same as a P4 at 3.2GHz
On top of this, Intel introduced something known as turbo boost with their i7. Basically it increases the clock speed of one core and reduces the speed of unused cores in order to gain better single threaded performance. So the i7 actually has 4 cores - 8 threads.
Hyperthreading has been reintroduced with the i7. It allows for 8 "virtual" cores. So each core can basically execute 2 commands more efficiently. The OS will see 8 cores.
And I agree the 955 is unlikely to be not good enough for you. It could even be overkill, depending on the other components in your system.

Thanks Guys ,,
So Everything is about "Hyperthreading - architecture - cache "
i think 4 cores with 3.20 of frequency are enough
because am using Dual core Processor "2 CORES"
So am i going to feel any differnce with the AMD PHENOM ii x4 965
And guys dont you see that there is a big differnce in the price between AMD and INTEL ,, For me am going to try AMD this time
so am i alright ?
Yes. What about your other parts? If you want more help, tell us what LCD monitor you have specifically on the resolution: 1360x768 or 1600x900 or 1920x1080? This will determine which Video Card will be best for your planned usage and budget.
