i use pcpartpicker the build i made was over 500 too
Then buy used, an AMD X4 processor plus a good 1GB GDDR5 video card from amd should do the job, it'll probably cost you no more than 400 USD, don't forget to get a good psu, at least a good 450W one.
Sadly,AMD regular desktop isn't out yet.so for best performance, Intel is it.
Now, as to going over budget. It's very easy to do, and it means you have to decide where you're going to cut corners, so to speak, to build the PC (Please choose wisely and don't cut too deeply into the PSU). Does it include monitor, keyboard, mouse (all which could be used in a dorm or residence hall or at home with a laptop,) OS and speakers/headphones? Those can eat up funds in a hurry too. You may want to consider, at least for some parts, used, but nothing more than say, 4 generations back on everything but a PSU and GPU, where two years old is probably the oldest you might wish to go.
