I would say if your budget is less than $130 or to be more specific, in the range of rupees 3000 to 10000, you can get a list of the graphics cards to choose from. The cheapest being GeForce GT 710 of around 3500 INR but this is something you should get if you have a really low budget and if you do not care about the video quality too much. Now, for a budget of around 6000 INR, you may get GeForce GT 1030, this is a very good Graphics card for beginners. You can game most of the games on medium settings with 50-60 FPS. The third choice is to stretch your budget to around less than 14000 INR and get Radeon RX 550. In this, you get a very good visual quality and edit 4K videos. Games will run on high settings on an average of 40-60 FPS. Also, the Radeon RX 550 will support games that the above two will not in the long run.
