You called the guy biased for wanting intel and Nvidia and then all you do is shove AMD on him, you're the ones that are biased.
He says he must have nvidia, which is ok for now since they have the cards to get unless your looking into x800xl. But on Nov.5 they will release the x1800xt in which he should compare it to the 7800GTX and then decide instead of just wanting nvidia. Both companies are good therefore you should look into both of them instead of just one.
As for Intel, AMD is better for gaming and he wants a gaming build. People seeing this suggest AMD knowing this, thats all. I too think he should get AMD but if he wants Intel then ok, his money. I am not biased against Intel in performance, just image(Intel is the only one of the two most people know about due to advertising, and threaten companies to use their processers only or else). Intel's performance for gaming just doesn't beat AMD. That may change someday and if it does then I will suggest Intel. Intel is going to a 9os architecture, and might be competition to AMD in gaming performance. For AMD fans out there, it could happen even though it might not look likely. No one predicted that Rome, the empire that ruled the civilized world and the military envy of the world, would fall like it did. Long explanation, but it all in all says why me and others push AMD for gaming although that might not be the case for everyone....
