I agree with the others, and only based on the way you were describing things previously - the brand shouldn't matter as they are both x86/x64 instruction sets. One of the bigger reasons consoles are running AMD is due to the BOM. Imagine how much they would cost if they were running i7's?
I don't think anyone is getting on your back about this as much as trying to understand your logic. FWIW (and I'm sure you know this) - the 360 was running a PowerPC core and the PS3 was the Cell. Games were ported to/from the consoles during the last 7.5 pretty well. The biggest issue with ports wasn't the hardware so much as it was whether publishers felt there was enough ROI.
As for the FX-8350, I'm super impressed with the processor (especially since the last AMD I ran was a K7), and I am running it overclocked in my SG10. It is what I consider a conservative clock as I've only messed with the multiplier; running 4.7ghz @ ~48C without issues since I've built it. In fact, the only issue I've had with the machine was when I attempted to set the BIOS setup to allow S3 standby. Something doesn't like S3, but I haven't dug in as I don't really care. The nice thing about this proc is that it scales really well. When I'm not gaming it runs Office-level applications (as this is my work computer) at ~9C.
