S III ROOT Jellybean

Looking into rooting my S3. Rooted the unbreakable D1 and flashed it to gingerbread, and a new kernel to oc it to 1.2ghtz.
Went to prison and forgot how to root and was wondering about the new Roms. Are there any non touchwiz jellybean Rom that will run smoothly on the GS3?
Feel free to email me directly please. charlesdeffendoll@yahoo.com
Also, what is the highest one can oc the S3 I want to be adventurous and oc to 1.8 or even higher if possible.
Please and thank you.
