I really hate to do this but:
I think I should send a word of caution about GPL.
As a point of reference block 5:

65754 blocks in 3 days. Equates to around 15 blocks per SECOND over three days.
I would hold off mining GPL and instead mine UFC or KED until the situation is fixed. I have already contacted the developer with some issues I have found in the code.
The issues are easy to fix but will require a block chain restart.
I hope I am mistaken, but at the very least caution is in order.
