I purchased a phenom 955 through 3B tech what a mistake that was I always buy from newegg or tigerdirect but thought I would try 3B tech because of a lower price I got all my other parts for a build from newegg when I put it together I had blue screen issues. I had to RMA back the MB harddrives talked with tech support etc. Ended up changing everything out accept the cpu and nothing helped so the obvious is the cpu. It took about 2 weeks to get this far. I had to fill out an RMA form and wait for 3B Tech to get back to me. They said WE CANNOT TAKE BACK A RETAIL CPU!. I did not get an invoice and there is no way to get one from thier website like newegg and tigerdirect etc. AMD wants this info and 3B tech will not help imagine that! I cannot believe it these sellers make newegg and direct shine REAL brite I'll tell you. I would hate to see someone else go through this also so just a heads up. Have to go to credit card way for help. Thank you newegg and tigerdirect that we have sellers like you!
