3rd gen CPU in a 2nd Gen Laptop Motherboard benifits are?


I've seen that 3rd gen CPU are compatable with 2nd Gen Motherboards. (rPGA988B) sockets. the biggest difference is the 2nd gen 2.0 PCI 3rd gen 3.0 PCI so the 2nd gen Motherboard cannot take advantage of this upgrade. the onboard graphics are Intel® HD Graphics 3000 for 2nd gen CPU and Intel® HD Graphics 4000 for the 3rd gen CPU. other then a bit a speed increase what other benifits are indused if one was to swap a 3rd gen CPU for that 2nd Gen cpu already running in the motherboard?
Code:
i7 2670qm base 2.2GHz turbo 3.1  45W about $80 US
i5 2520m   base 2.5GHz  turbo 3.2  35W

base speed slower the i5 turbo speed slower then i5
will the extra 4 threads increase performace?


i7-2760QM base 2.4 GHz turbo 3.5  45W  $90 US
i5 2520m     base 2.5GHz  turbo 3.3   35W

base speed slower then i5 trubo faster by .2
will the extra 4 threads increase performance?


2nd gen i5 2520M base 2.5 turbo 3.3 35W
3rd gen i7-3520M base 2.9 turbo 3.6 35W around $80 US
both dual core
I am asking because I keep hee hawing between trying to figure out what benifits I'll see if I change out my i5 2520m which runs base speed of 2.5GHz 3.2GHz turbo, the most I've ever pushed this CPU is 3.02GHz rendering with blender. CPU set on powersave, if I set it in performace mode it crashes blender. nevertheless, I am only curiouss to how a 4 core 8 threads i7 2nd gen CPU will benifit me over what I already have.

then comes the 3rd gen i7 dual core or quad core that are also compatalbe. trying to keep the price down to 100$ US or less for the CPU. so the 3rd gen dual core i7 3520m will cose around the same price as a 4 core i7 2670qm.

Code:
2nd gen i7 2670QM  base 2.2GHz turbo 3.1 45W around   $80 US
3rd gen i7-3520M     base 2.9GHz turbo 3.6 35W around   $80 US
2nd gen i7-2760QM base 2.4GHz turbo 3.5  45W  around $90 US. 
2nd gen i5 2520M     base 2.5GHz turbo 3.2 35W already installed.
which is the better CPU?

will I actually see a difference in performace adding 4 more threads?

in general if you have no problem at all just give me that 100$ instead of buying something which will not give you anything...
From the other hand if you want to speed up something or you need to improve something just tell us about that

haha I actually know someone else I can just give that 100$ to instead because that was my other hidden option...

yeah that is what this question is all about how much speed would I actually increase if any adding 4 threads does not actually add speed due to 4 more threads working along with the other 4 threads. Theoretically having more people helping get the same process done it will be completed sooner then having less people working on it. same should go for cores or threads seen as cores.

I just like an experieced option before I waste 100 and see no benifits

with blender doing videos, having 6 or more loaded into one session for cutting and splicing together adding special effects and sound, then rendering. so it's mostly blender is what is taxing the cpu, other things is handbrake vlc web browzing.

MY LOGIC IS: more threads at same base speed 2.5ish with four more (cpus) threads should it not make it a lighter load on the system as a whole?
if I drop the base speed to 2.1 or so still with 4 more cores / threads it sould still elevate the stress on the system as a whole.
should it not?

8 cars with the same amount of horsepower pulling 1 ton can get it done eaiser and faster then 4 cars of the same specs.
even if you have 8 cars with a little less horsepower pulling 1 ton the total load will be distributed to all 8 cars but the speed may still be slower, even though the over all stress will be lessened.
thats the best I can do with an analogy. But I am still not sure about cpu's because it may still have to do with if the software is written to utilize threads if not then it still does not matter.
I do not know if they have gotten past that limitation.

maybe nothing I can do to make it run smoother like when I'm only using 2 movies to splice together. taking in that I have proxied all of the movies too.\

i5 2520M
