Honestly you should build your own as previous posters have said (or get a friend to). You could get a very powerful gaming rig for that budget and have quality components too. For example, a sandy bridge i5 build would look as follows: mobo 125-130 CPU 210 RAM 80 PSU 80 495-500 Then add a nice graphics card (~$300), HDD (50-80) and a case (80). Well within your budget and much higher performance than what was listed previously. Also Windows 7 professional can be had for $30 if you have a .edu email. (i.e. student)
