For a Xmas gift for the GF's daughter I want to build a gaming computer with her. She's really into gaming (though, I admit I have no clue which games). She has an old Dell gaming machine that seems to be on it's last legs. I'm actually not even sure it works anymore. I looked at it at some point and it's a good 5 yrs old, so you can probably figure the capability is pretty limited by today's standards.
Anywho, I've built computers before, but never anything for gaming. What should I be looking for in terms of specs? CPU, GPU, RAM, etc. I'm trying to get the whole family to contribute and build something fairly badass for her. I'm thinking the final budget is going to be $1000-$1500.
