Good choice, mommy. My dad bought me a video card for Christmas when I was 14 (though this was in 1998), and I learned a lot about computers installing it. I started off just wanting to play better games, but ended up getting interested in computers in general.
Fast forward another 14 years and I'm a software engineer making triple the national average salary. Computers have been good to me.
Just read a little more about this video card:
Cons: 2x6pin PCIE connectors required. This is only a con if you don't plan to overclock, as then the supplied/available power is overkill.
Does this mean it won't fit the gaming computer I've already purchased??
