My New computer!
I think my brother did but I spent under 1,000 dollars on my new machine. But besides all that. Whats the point of transferring over your graphics card. If its not PCIx16 its not worth it. If you going low budget or not to much then count out Blu-ray or HD DVD roms or burners. I looked up some Blu-ray ones and it was 500 dollars. But if you like give us more info on what kinda gaming you want to do. Then we can go from there. Jana can do anything on what you build as for music and work. Its the gaming part I like to know more of.
