DP for Adaptive Sync

[Raphael937]

Hello, Im looking forwards to change the HMDI cable from my Alienware 240hz. After nvidia release the G-sync adaptivity i would like to know which is the best DP to receive the free-sync at 240hz according to some information i was able to dig it needs to be a Displayport 1.2a but I'm unable to find any on amazon. If someone could help me link some options, that would be great.

Any DP cable will work, DP cables don't affect support for features, like adaptive-sync.
