Was thinking about overclocking and see threads very pro overclock and I got a i5 3570k and was thinking of overclocking to 4.2ghz which is a 800mhz boost which sounds good but then I started thinking about the turbo boost which is 3.8 so would my improvement only be 400mhz and how much performance would I gain from this overclock

I have a 3570K and got a small gain from overclocking. Now I leave it at default 3.4 with turbo boost to 3.8 and it runs fine. If you want to overclock you'll have to buy a new, larger CPU cooler first since it creates a lot of heat. To me it wasn't worth it but opinions vary.

By default, those turbo boost frequencies are not achieved on all cores(one will run at 3.8, another at 3.6 and two at 3.4 for example. If you overclock from the top as in you increase the TB frequencies, you may find yourself in a simmilar situation, but with higher frequencies. If you overclock the base frequency, it's another story, but you will have more heat output.
Regardless, those 400hz are not insignifiant as they represent 10%. So if you were cpu bound in a game(scarcely the case, but i'm giving an example) while going from 50 to 55 medium FPS doens't seem like much, the increase in minimum framerates may help more.
What you need to take into account is whether you need teh extra power or not. Overclocking for the sake of overclocking is meaningless.

i5-3570K
If you have TURBO on which you likely do then the Max Turbo is 3.8GHz.
It's actually slightly more complicated than this, so I'll just show you how I overclocked my i7-3770K, because depending on HOW you overclock then 4.2GHz might not be a 400MHz above 3.8GHz. You can change multipliers for example.
Your motherboard may be setup differently. You can even just try the built-in overclock utility first to see if it works. Don't forget to run:
a) Memtest86 www.memtest86.com
b) Prime95 or similar
c) Intel CPU diagnostic (mine sets my i7-3770K to 3.5GHz, no Turbo, and I have to reboot to get my BIOS settings back. sigh. Maybe not pointless to use, but it doesn't validate my overclock)
Monitor CPU freq under:
Start-> Task Manager-> Performance-> CPU-> "Speed"
1) TURBO ON
2) XMP ON
3) manually set the MULTIPLIERS for 1,2,3,4-core configurations (ended up with 43, 43, 42, 42)
I could have tweaked a bit higher by messing with VOLTAGE but I didn't want to bother. I have adequate cooling, but messing with Voltage will raise the temperature a lot more than raising the frequency. Some people raise voltage just a tad but a stable 4.2GHz under full load is just fine.
So...
*normally my full load performance would be about 3.6GHz. Going to 4.2GHz raises my performance for programs that benefit by almost 17%. Like HANDBRAKE for converting video. That scales perfectly.
It may or may not make a difference for games. It depends on the game though I'd expect between 0% and 10% depending on the game, settings and GPU.
