Well, I'm just comparing X58 to P55 here - saying that given a higher budget x58 makes more sense than P55 IMO. And sorry I really disagree that dual gpu at least capability isn't a key feature of a gaming PC. It can greatly limit future upgrade potential.
On a high budget sure, X58 all the way, though I'd still consider my actual use of the machine. As for dual GPU what I meant was you dont need 2 cards to classify it as a gaming PC. A board with dual slots is a must I agree, but even x8 wont limit you unless you have a GTX480 or HD5870 sitting in there. At which point if you can afford two of either of those cards then you can afford a proper X58 or 890FX mobo.
