This a good Upgrade

You're changing the parts that matter the least, imo. Unless you're having troubles keeping RAM usage under 12GB, you should be fine with 12GB. I don't have any experience with 1600MHZ but many people on forums say there isn't much of a noticeable difference.

If you're needing the features in that motherboard, go for it, but if you are upgrading JUST for the performance increase (if any) I don't think it's worth it.

Maybe in the benchmarks. Get an SSD and u will see difference for sure.

Than only new CPU will speed up things.

Oh, I see that u have the SSD already.

So, only CPU will make a difference that u can actually notice.

Well my CPU is overclocked to 3.8, so? Should i just stay at what i have.

IMHO, yes. There is no speed up on mobo and RAM exchange.

I would not do it. Its just getting more of the same.

Check this compars... And u decide if it is needed to change.

It would be bit more noticeable with 3770K
