For gamers, graphics cards are essential, but do you really need a $500 graphic card to enjoy the latest games as of 2013? Well, it really depends on how happy you are with the quality of graphicws you are getting, some gamers are happy when getting 25-30 FPS in thier games, for hardcore gamers they won’t be happy un till they get 60+ FPS in thier games, but that would come at a cost ofcourse.
The fact is, you can actually enjoy all the latest games even with a budget graphic card, range form $100 - $300, at the moment there are a lot of cheap budget graphic cards less than $200 that will play all the latest games such as Bioshock Infinite, Farcry 3 or Crysis 3 at Medium to high quality, and you will still get a very good playble experiance from the game, it might not run at 60+ FPS at 1080p, but you can get at least 25-30 FPS at high quality, which if you are happy with that, it’s atually a very playable experiance, and you actually save a lot of money as well.
At the moment the GTX 650 from Nvidia is a great option if you are looking at a graphic card under $125, you can even get the GTX 650 from many places at around $100 or under, whis is a great deal as the GTX 650 can play the latest games at a reasonable quality, you can play the latest game with this graphic card even when you have an old CPU. As most of the work load would be handeld by the GPU it self.
