AMD Phenom II 550 x4 :)

Yes, I have one.... AMD Phenom II 550 with 4 cores (after unlock in BIOS). The CPU runs stable up to 3,6GHz, in different Benchmark test even in a 24h CPU burn in Test. I run the CPU with 3,4Ghz that´s fast enough :) I´m lucky one.

So maybe you will try your luck 2 ? Have fun.
