Need for Speed ??14, EA (Electronic Arts) platform for networking related issues.

I recently played Need for Speed ??14, his career has been completed and is currently considering to buy a genuine KEY network play, but considering the fairness of the game, do not know whether this anti-cheat system platform, such as COD7 (Call of Duty 7) of the STEAM platform Anti-cheating is quite powerful. Cheating of course, but relatively few.
has been considered for nearly two weeks, check online whether EA anti-cheat features and no fruit. So ask you reach people, especially the players have to start NFS14 genuine:
1.NFS14 platform sports network if there cheating.
2. cheating is serious. (Such as nitrogen with a modified device to open limitless, ah, ah these, and so infinite skill)
3. Is it worth buying genuine KEY (identified in a single KEY Taobao about ￥ 90 ).
buy if there are genuine and in playing with friends online, more trouble parsing it. It is necessary to add my QQ: 77958288
