I just purchased the new AMD Phenom II x4 955 BE for my GIGABYTE GA-MA790FXT-UD5P AM3 board in a XCLIO Windtunnel case. (all findable at newegg) So, my question is I'd like to get a Thermalright Ultra 120 Extreme, but didn't know if A.) it would even fit in my case (the case is a full tower and huge! so, don't think it should be a problem) or B.) if it'll even go with my socket. i see a backplate is needed for AM2 boards and such, but i can't find anything online about AM3's! if it won't work, can anyone recommend anything else? i'd like to get a heatsink ordered today so i can get my new rig up and running. Thanks for your help!
