i have a Sapphire Radeon 9800XT and boy does it get hot, plus i had to set my AGP speed to 4x instead of 8x because my games kept randomly crashing, which a lot of people seem to have with the same card, so you might also want to invest in some extra fans, and remember that the graphics card will want power directly from your PSU, so if you are gonna add lots of fans you might want a better power supply...
having recently got a new pc myself i would just like to say WOO!
