Not yet. My last PC was going on 6 years old, and opening up a scene with more than 2 genesis characters would cause it to crash. Repeatedly and spectacularly. That this one can handle 7 genesis without any stress - or crashes, or even potential crashes - amazing, astounds and fills me with a maniacal glee. There are so many scenes that were theoretical, which I can now actually do!
Mind you the processor was running at 99% and it was using 8GB ram, but still, it worked!
