After a lot of reading of reviews and comparison of benchmarks I decided to wait until AMD brings out a revised Bulldozer CPU to a better price. So far I’m going now with a “new” AMD Phenom II X6 1055T Processor, which was with 129$ and free ground shipping in special at Direct Canada. To keep it cool for overclocking I spend her a Corsair Air Series A70 Dual-Fan CPU Cooler, which is in fact a monster and was for $29 at NCIX. Be sure when you buy one, that you have enough place in your case. Specially it can get problems with the installed memory. I was lucky and my G.SKILL Ripjaws X memory was not to high. Finally I overclocked the CPU to 3905.87 MHz which stays calm and stable at 43 degrees under prime95 and all other benchmarks. With the stock cooler it was going up to 62 degrees. Without load 24 degrees.
