Firstly, what are you gonna do with the system you'll have?
And secondly, what is your budget?
It's mostly for gaming (mainly TF2, which doesnt require much), but also for just general everyday use. I want to be able to run new games (obviouisly). Most important is huge boost in TF2. It's time for an upgrade, in general.
Budget is somehwere south of 2k usd for entire thing. For graphics card looking for something under 500.
