Intel has been a spoiler in the GFX market for the longest time.

Every laptop I've had that has discrete GFX has had recurring bugs with both Firefox and Chrome because of the two-GPU situation. I would have the hardest time documenting what was going on, they'd fix the bug, then in the next major release it would break again.

MS just gave everyone with a 4th gen proc another reason to open their wallets for something newer.

Lol, I'm on a 4th gen because my wallet is empty. But I like to think that it's because performance improvements up to 8th gen were pathetic.
