you could easily get a low end - mid range graphics card on that quite cheaply from what I could see but honestly if you want to play modern games comfortably and not rage at them constantly you should get an i5 quad core CPU or higher. I went and upgrade my graphics card without thinking and now I have a super powered graphics card but my CPU can barely run at the high settings because it takes too much processing power to do so. What I would do is save up for $600 - $1000 ( This will pay for a nice graphics card too ) and then that should be more than enough to get at least a pretty nice gaming computer and not have to deal with the stuttering or FPS drops that come with a underpowered CPU.
Loads of games now are dumping lots and lots of resources either through bad optimisation or are pushing the boundaries really hard so if you think you're going to be able to play games on a cheap computer these days you've got another thing coming, simple 2D and 3D games yes, but none of the big titles that are coming out now. I just recently had a fit against Call of Duty: Advanced Warfare because when I tried to start it up to check if it would even work on my PC it blocked me because of how old my CPU was and I suspect it's only going to get worse from now on.

Thanks for the tip!!! I'll keep that in mind
May be a while before I can upgrade my computer unfortunately. Knowing what people use now may help me in the future though.
