I think my PCs have always been Intel - I think the earliest I had was either Pentium II or maaaybe a Pentium I - (it was on a hand me down PC running Windows 95, so I think it must have been).
If the new AMD platform was out earlier, I probably would switch over. Not that it makes a huge amount of difference at this point.
I've tried both and never really noticed that much of a difference - I feel like graphics cards tend to have more issues than other components anyway (based purely on my own PCs).
