8 Core CPUs doesnt make sense. A lot of software out there to convert media files still doesnt support that amount of cores. An AMD Phenom II x4 /x6 or an Intel core i5 / i6 CPU is absolute sufficient.
Since I own an i7-860 with HT (8 logical cores) the x264 encoder scales usually from 50-90% CPU-load.
So I thought, one might improve encoding-power by useing 6 or 8 physical cores, especially since AMD has lower prices.
In general - yes, you mostly won't be in need for more than 4 cores. ;)

Respect to HatoriTakaya for wirting all that stuff. I didn't want to read everything due to it's lenght so i just want to respond to some little details:
A PSU with 750W ist highly oversized for shinigamidaiko's use.
My system contains the former mentioned i7-860, an AMD 5850, fully stocked RAM-Slots, 4 Fans, 8 Harddrives.
I use an old BeQuiet! 530W PSU. To be honest - sometimes i think, it has to work a lot, but it never made problems.
Most PSUs have a power range with the best efficiency, mostly between 60% to 90% load if I'm not completly mistaken.
So if you use a 750W PSU for a system without dedicated graphics card, the system load will be under 25% all the time when idle. I you think this is a good thing - wrong :)
If you want to do it right, buy a quality brand PSU (BeQuiet!, Corsair, Enermax ... they are more expensive) with cablemanagement and think about upcoming connection standards and on what you would like to upgrade in the future.
Cablemanagement is something, I don't want to miss anymore today, since i never had problems expanding my setup, but it doesn't come for low...

I'd recommend to use the 3770K without OC if not needed, because it has its own turbo-mode and will adjust to normal use.
However if you have special tasks and you want to encode a whole day, just OC for this day.
With ASUS MB and the K-CPU it will be very easy to OC. If you want to stay silent, buy a big tower-cooler for like ... 40-50$ max.
More important it is how big your chassis-fans are and on what rpm they run.
I recommend 120mm+ fans @600-1200 rpm.

SSD: Samsung SSDs are good. Usually 64GB should be enough for 64Bit Win7 and most software, since gameing is not a factor.

Motherboard: Don't pay too much for things you never use. I wouldn't tell you to buy a $75 low-price noname board, but you don't have to pay $200+ for something you don't need, since it won't improve your performance in the end.
It's always a wise idea, to think about future expansion slots.
Important are SATA, PCI-Ex1/x4 slots.
And yes - you should not buy the ASUS MAXIMUS V FORMULA MB. It's too expensive and has slots and features you'll never use :D
