I have a Dell Studio 540; Intel Core 2 Quad CPU Q8200 @ 2.33GHz, 4 Cores, 4 Logical Processors. I want to upgrade my graphics card and I need information on what is some of the best I can get within a reasonable price. I'm not too experienced with these things so all information will helpful. I am also not sure of my current graphics card because I bought this Dell off a friend. So if there is a way to find that out as well that would be great. Thank you!
