hi. i want to add a xfx 7600 gt card to allow me to better play some games. my pc has a card in it with a wintv tuner on it. i have the extra pci-e slot but did not know how or if i could use both cards. will i have trouble running the two? is there anything i will need to know? i know i need a better power supply but just not sure if there is anything i need to do to set up the new card so i can also keep the existing with the tv tuner. i'm going to try to post a few pictures as well as my computer info. thanx in advance for any help, advice or suggestions.
