Summary: I bought this processor to replace the older Athlon X2 processor in my desktop. The X4 620 has made a noticeable difference in the operation speed of the PC, and runs within reasonable temps even under load from heavy gaming with the included factory heat sink.
Summary: An awesome processor, good bank for your buck! I can play Crisis 2 on this CPU @~ 30FPS on ultra with a GeForce GTS 450, minor lag during loading, but that's expected without L3 cache, like I said good bank for your buck. 1/2 the price of a Phenom for about ~1/2-5/8 the performance. >1/2 the price of an FX for about >1/2 the performance.
Summary: I have always deemed AMD the best Bang for the buck. This is why I waited so long to upgrade. The Athlon's I had were being Uber Used. Having maxed out the 939 series (gaming has passed it) I had to upgrade just to play. Now I have 4 Cores! it is stable, allows overclocking on the fly (reboot MB bios change) and as you know, overheats only in a hot house- I always have the air on and a super-cool case.
