May be...

hi i am going to put an os down on my ps3 but not sure which is best also is there sumwere i could download watevr u reccomend

and how would i install on ps3?, thnx alot. =)

Linux

It is free to obtain, so I'd go with it

YOu can put the Linux on a flash drive, plug it into the PS3

THen go the the part of settings where it says install other OS

then choose the flash drive and Linux

and you are putting a new OS on your PS3
