Well with the 2012 Bonic Pentathlon starting in about a month, it's time for that upgrade I have been waiting for. I was going to get a FX-8150 and try to clock it at 4.2Ghz. From my research I don't think AMD has any more 8-cores on the horizon, if I missed something please let me know. I also need some advice on GPUs, my primary goal is to run Milkyway@home, from what I have seen a 6930 or 6950 will give me bigger bang for my buck when compared to the 7850. I did read on one forum that the 7000 series runs better with the bulldozer than the 6000, not sure if this is true so I wanted your take on that as well. Let me know what you guys think, I am going to use this as my primary rig, but the vast majority of it's time will be spent as a BOINC rig so I want to build it as such.
