Questions about AMD and Intel CPU

Hello ? Today, I saw "TechSpot's PC Buying Guide" and I got a question regarding processors.

I knew that AMD Phenom II X4 Processor is cheap and Core i7 is expensive.
But I really want to know which processor is faster, specifically:

AMD Phenom II X4 965 Black Edition Deneb 3.4GHz
AMD Phenom II X4 940 Deneb 3.0GHz
Intel Core i7-950 Bloomfield 3.06GHz
Intel Core i7-975 Extreme Edition Bloomfield 3.33GHz

Can anyone arrange those 4 processors ? (Fastest is "1", Slow "4")

1)i7 975
2)i7 950
3)x4 965
4)x4 940

if you want to build a gaming rig then you should consider getting a more powerful video card, not a more powerful CPU. A core i5 or x4 965 should be more than enough for a good gaming rig.

Take a look at http://www.techspot.com/review/195-mainstream-quadcore-cpu-performance/
for a great comparison. Quick note - i would look at the i7-860 instead of the 900 line. Different socket motherboards that are cheaper and should meet all of your needs.
