It's nice that everybody is entitled to their own opinion. Doesn't mean it's true, fact or has to be agreed with though. In 2010 the comparable card at that time was the GTX 460. I know people still using the 460 and 480 for a lot of titles. Not the most demanding titles, and not on Ultra settings, but it still games.
Some of your posts are based a lot more on opinion than fact, so just watch the opinionated posts and stick with facts. Blanket statements, that are entirely inaccurate will get you sanctioned quick here. For example,
AMD cards don't have enough driver support and you will run into problems with certain titles.
That has no basis in truth. While it's true that AMD does have some driver issues in certain areas, it's equally true that NVidia has them as well. My R9 290x plays any game without issue so long as I'm not trying to run with settings only intended for NVidia cards enabled. Some of that may or may not be patched up at some point, but regardless, the games still play fine. There are no games I can't play at a high level due to having an AMD card. Making statements to the effect that buying a certain card prohibits you from playing specific titles is simply nonsense.
And furthermore, IMO, any piece of hardware that costs two hundred bucks or more, better damn sure last five years at the least. Not everybody is foolish enough to believe they'll still be able to use the hardware at the same performance level in five years, but to still be able to use it at SOME level is an expectation I believe to be realistic. Even if you need to pair it with a second card at some point down the road, which is what most gamers end up doing anyhow, that's fine. I expect most the issues with SLI and Crossfire that do exist, to be non-existent by then anyhow.
