Yeah this will work. Also, I'm not sure if this works but I'm guessing by theory since the shaders are made by pixels, a card with more pixle rate will be better.
You can look at a website, hwcompare.com this website let's you compare graphics cards and which are better by their specs. It also tells you the pixle rate and stuff. You should look at some other radeon and Nvidia cards, this one will do the job though.
