Additional Comments: I'm looking to build a gaming computer which can play games over the next few years with moderate upgrades (e.g. $100-$200 video cards every year or two). I'm used to playing at low graphics settings, so I don't expect to achieve super-high end graphics, but some eye candy would be nice.
I know my video card is currently lacking (GTX 260), but for $50, I just want it to hold me over for the next several months.
I was hoping to get some comments/suggestions for me to stay closer to my budge of about $600, or have a more "future-proof" system for about the cost of what I have listed below.
