Hey friends! i have a pc with an i3 processor and a nvidia graphics card in it. Generally I keep upgrading my nvidia graphics card driver on a regular basis. Now I am in need to use some graphic card that is best for gaming and other such functions. I don’t want my system to work slow. So what do you think, should I go for some other graphics card? Is there any way of using my existing nvidia graphics card with an another one installed. Will it work that way?
