[Solved] How Far can I redline this baby?

Sup people. I am going to get the Phenom 2 955 Black Edition Cpu. I'm also going to buyARCTIC COOLING Freezer 64 Pro 92mm CPU Cooler. It was recommended to me because I have a micro atx board, and it looks like it will fit. I am currently using a Phenom 9600 2.3 Gig Black Edition, and I am overclocking that to 2.7 Gigs on stock cooler. I have a Rosewill Case (not the greatest case, but it works). I found that by taking off the side panel, my temps go down a chunk. I was wondering, for those who have the Phenom 2 955 black edition, how far should I be able to overclock it, and keep it stable. Like I said, I'm going to use the ARCTIC COOLING Freezer 64 Pro 92mm CPU Cooler instead of the stock cooler. I know I probably should get a better case like the Antec 900, but my current case works, and I really don't want to xfer all my stuff to a new case. I just put the new board in a couple of weeks ago.
