Im going to give my opinion even though this question sucks.
AMD is better. When you weigh price in. AMD is not far behind Pentium in performance, but its price is waaay lower.
If you want all performance and dont care about money, obviously go Pentium. And while youre at it, get a FX 5800 Ultra because it outperforms the 9800 Pro, and buy everything that costs more but has that slight edge.
but the faact is people dont have all that money, and weigh price into their descision. We want the best, while not going broke. hence why I have AMD 2400XP instead of P4 2.4ghz, and a Radeon 9700 Pro instead of 9800 Pro or FX 5800Ultra, a 2mb cache HD instead of 8mb, OCZ pc3200 memory instead of Corsair, MSI's k7nl2 nforce2 board instead of Asus's deluxe version, and the list goes on.
So yes, price weighed in, AMD is much better.
