Intel vs AMD
The only thing AMD ever had going for them was value vs price. That has disappeared in recent years, hence why they are loosing market share. Their performance was mostly on part and in some cases exceeded Intel's chips (with the athlon XP line / Server class chips), but when they increased the price, after being a 6 year AMD guy, I went back to Intel, because , hey they are the top chip maker, and their products just seem to perform better in my experience. I have found nothing to beat an Intel chip on an Intel chipset.
Ready for flames!
