Worth upgrading: i5-750 v i5-3570K

[real world]

Hi guys, thanks in advance. My current gaming rig is an i5-750 based system OC'd to 3.6hz. I use it for gaming (GTX 670 gpu) exclusively, mainly BF3. I have a Microcenter nearby and their most recent sale has put the i5-3570K on sale for $169, with a $40 discount if u bundle it with a mobo. This has me wondering if I should take advantage and upgrade my PC. My question is whether or not it's worth it to make the jump.

Is the difference in performance between the i5-750 vs the i5-3570K worth it? Thanks in advance.

It is worth it as you have a gtx 670 gpu. You will obviously need a new motherboard.

You know when I first installed my GTX 670 FTW I was running my i5-750 at stock. The stuttering I was experiencing in BF3 was unbearable. I ended up OC'ing the 750 for the first time, and the stuttering went away. I was shocked to learn that the i5-750 at stock was bottlenecking my GTX 670.

Yes I would need a new mobo. I'm thinking of going with one of these two. $15 cheaper, and my personal appreciation of Asus motherboards, has me leaning toward the LK.

ASUS P8Z77-V LK LGA 1155 Z77 ATX - $120

OR

ASRock Z77 Extreme4 LGA 1155 Z77 ATX - $135

I would probably recommend waiting until Haswell unless you're not getting the performance you want.

Also, those motherboards are overkill with a Core i5-3570 since it's only limited unlocked.

Oh my bad, it's the K version. The i5-3570k is what I'd be buying. I forgot the K is important. Doh!

Oh. I blame Intel.

Anyway, your current CPU isn't really all that bad. Unless you really need more performance, I'd recommend waiting for Haswell so you get a bigger upgrade for your money.

While it is possible to do a little overclocking with the Intel® Core™ i5-750 you are not going to get the performance from it that you would with the Intel Core i5-3570K. However my general rule is 3 years before upgrading so I would look for a way in which I can pick up my performance right now and wait a little longer for a new system.
