Unless the current cable is defective, that upgrade probably won't make a difference. The speed of the cables is mostly irrelevant for an MMO, the big bottlenecks are your hardware (PS3, modem, router) which are all basically working or not, condition of your connection (probably the main issue), and the servers that handle the game.
That's not to say that the cable couldn't be bad and that replacing it won't fix the issue, but the speed of the cable is not the issue.
