[theory]

I was wondering weather it is physically possible to upgrade the graphics card on crt iMac ( it has ati ultra card). The graphics card is fine for most of my work but I really wan't to play RTCW, and it needs a graphics card with a GPU.

Unfortunately, no. The graphics cards in the newer CRT iMacs (ATI Ultra) are soldered on to the motherbaord and cannot be replaced.

you can put a Vide SO DIMM in to boost the Video ram. or get one of those rare Voodoo Mezzine slot card that would give a boost but they are kind of out of date...

hes a slot loaded, the other options were only for rev a or b tray loaders

sorry dude, no upgrades possible
