A list of graphics card that can support all games

Any graphic card will do, the amount of onboard ram is the key the more ram the better will be your experience, more ram = larger frame buffer = smoother game play, there are of course some limits, some games are more cpu dependent than others, the only way to find out is to look for reviews for any one particular game, if the game is worth it there will be a review somewhere...:)
 
This is simply untrue. more than 512mb is pointless for low resolutions and even at high resolutions having more than that is very far from the most important feature of a video card.
 



Lol... Really?

Lets see how well you do with 32gigs of 800MHZ ram, good luck now.
 
In terms of just running any game then any DX12 capable graphics card would do, though thats just the ability to run them, actual performance would vary quite wildly.

@Dokk
What applies to system memory also applies to VRAM, capacity does not impact performance until you run out of it. At 1080p, 2GB is enough for most games, with 3GB only becoming necessary at 1080p if you drive up some settings in certain games (Crysis3, modded Skyrim).
 

Just foolish . You kind of people only make others fool . Some years ago when i didnt know much about graphics card and had a 8400gs . I was having 2 gb ram and my games were lagging badly. I thought 8gb ram would change my experience but all wasted . Nothing changed . No increase in fps. It was my biggest foolish decision. but im proud that i did this mistake because now i know wether 8 gb or 2gb both are same for the games of present generation. If you are foolish why are you making others fool . First you should check that whatever you are posting is correct
