Yes, you can just adjust your settings and you should be just fine. Do you have a target fps that you are trying to achieve. A lot of times it depends on what the gamer wants. Some gamers like max settings and still want over 60 fps while they play while playing at 1080p. Personally, I don't think wow's graphics are amazing at all so I turn all settings down and I might raise a couple of them if I feel like it. I just built a budget PC with an A6-6400k with no discrete graphics card and turning all settings down, while out questing I got up to 100 fps at 720p. Hope that helps a little.
