Graphics card upgrade?

[Tabletski]

16GB ram with a 128mb SSD, and 1TB normal drive for stuff. I am almost ready to order an i5 3570 but am at a loss as to the S,K,T variants
I could only find a 3570 S - which seems to mean lower operating temperature. I have not done a part master search yet to see where is the cheapest. I don't get paid till the 15th so waiting till then.
Thanks for input.

K = Unlocked multiplier = great overclock ability.

S = Lower power consumption, not great OC ability.

T = Even lower power consumption, not great OC ability.

First view the standard clock speed of variants and the turbo boosted Link:- ARK | Compare Intel® Products

Why would you want a S or T vs a K? Link:- Low-Power CPUs: Specific Applications Only - Core i5-3570K, -3550, -3550S, And -3570T: Ivy Bridge Efficiency

As you don't need a low power consuming CPU with lower thermal output at the sacrifice of CPU performance in apps the K is your option IMO.

A 4.x GHz overclock on air cooling is easily doable on a K variant CPU.

Ahhh, more input, bliss. I can now make an informed decision. Thank you.
