I have AMD, been able to max most of the games since 5 years back to date.
If one does for some odd reason remove it while it's on - then it's their own fault.
Although, these are pre-dated chipsets and I'm sure they've fixed whatever issue that might've been.
As Intel hit the market before AMD did, as far as I know, so Intel had the monopoly which lead to AMD not having as much market, thusly they wouldn't be able to use as expensive materials due to economy.
Prove me wrong if you wish, I don't care.
Brand isn't what's driving me.
