hi everyone, i recenlty bought a new pc for recording and uploading game footage. i dont know very much about pc's so i was loooking for help to upgrade it. the pc is ok i can get good footage at 720p but when i try upgrading the picture that lil bit more it makes the recording lag. any idea on what part(s) i could upgrade just to let everything run a bit smoother? this is the pc i have bought..http://www.currys.co.uk/gbuk/computing/desktop-pcs/desk...
