I was just wondering if anybody knew if the x38/x48 were more future proof then a p35 for example will all cores that are compatible on p35's compatible be on x38. I know one has pci 2.0 but by the time that matters wouldn't you say it is logical to guesstimate that nividia will be a couple generations past what they are at now? and if that is the case then your cpu would be a bottleneck for the gpu so you would need to buy a new motherboard anyways lol.
