With Borderlands 2 it's a great buy for sure. I don't have that deal available and I've already pre-ordered borderlands 2 on steam. I just find it weird that 7950's are having to be flogged off for so cheap to compete when they are clearly a step above the 660ti in my eyes.
I think it's mostly due to nvidia's super marketing power. Everytime I buy video cards, my initial reaction is always to look at nvidia first. It's strange.
It's relevant because of drivers. Without the company around to make drivers, your card is an expensive paperweight. Just ask all of the people who bought 3DFX cards back in the day. nVidia isn't going anywhere, so I feel safe recommending their cards. AMD is practically penny stock. Recommending one of their cards is like recommending a Blackberry to someone looking for a smartphone. nVidia is an American company and they seem to be really good at marketing their stuff in the states. Their cards usually come bundled with a game or a bunch of games, and have free shipping. The reverse of what Fusion said is true in my anecdotal experience. All of the PC gamers I know IRL buy nVidia cards. I literally don't know anyone who buys AMD.
AMD are an American company also, one renown for bad or non-existent marketing, but still American. ATi were Canadian, but it's been 6 years since they became AMD. I don't remember ever saying everyone I know buys AMD GPU's, Nvidia sells better here also because they have a much stronger brand presence and the image of better drivers. I personally have had equal trouble with both companies products and drivers and find friends with both also have troubles of equal value on either side, so buy whatever performs better and looks the most future proof while having the features I want. Nvidias cards have fetched a premium for a long time now because of their better perceived image and apparent more valuable feature set. To me, they aren't always worth that extra money, to about 60% of the general PC gaming market though, they are for whatever reason.
I don't think he said anything about their driver stability, he just said you are more likely to wake up tomorrow and AMD is no more than you are with Nvidea. That being said I'm not too sure. Both companies have their worrys. Nvidea mostly because they have no x86 cpu division.
