Buyers remorse?

I was brought here by my curiosity. Here's a little background:

I have no experience with GPU cracking. Earlier tonight, I purchased a Radeon HD 5970 for $90 even. After completing my purchase, I began to read more about this specific GPU.

Fast forward 30 mins.

Correct me if I'm wrong, The AMD Radeon 5970 is no longer supported with oclhastcat? I purchased this card after referencing GPU estimations from the web page pasted below.
