Two years ago I got a Dual 1.0 GHz MDD G4 with an nVidia GeForce 4 4800 Ti. This year my younger brother got a Dual 2.5 GHz G5 with an nVidia GeForce 6800 Ultra. However, it originally came with a Radeon 9600XT because they could not ship the 6800 quick enough. Since I help him out with his computer quite a bit, he gave the 9600XT to me since he didnt need it anymore. However, I'm pretty sure it wont work in my computer, and I really didnt want to just stick it in and find out. Does anyone know if it will work with my computer? Or no?
