Newegg has a few cards left. I picked up a 4995, (one per customer). Then I tried to buy one from EVGA, (I hit the site shortly after they were put up for sale).. but when I tried to buy one, it kept giving me a "Bad Credit Card" error message at the final part of checkout. After trying multiple cards, multiple times, (all have plenty of room for the purchase), I gave up and went back to Newegg and bought the 4992. The 4992 is the same speed it just has the stock cooler.
Right now Newegg still has the 4992, which has a decent overclock. (and some stock speed ones).
