Hello, I'm running a 1ghz 17" powerbook. The spec sheet says I have a GeForce 440 Go but my system profiler reads Geforce 4mx. Just to clarify, I have no idea when it comes to graphics cards. My concern is that, I think the anomaly might arise from an upgrader (?) I used on the Halo for mac game disk. Like I said, I have no idea when it comes to this stuff but in retrospect, I'm pretty sure the upgrader was for Radeon cards only. Now, I'm wondering, did I possibly do harm to my graphics card? I actually thought I remembered system profiler saying I had a geforce 4ti. In a quality hierarchy, is a 440 better than a 4mx or is there an equivalence there or could you possibly point me in the direction of any resource where I could learn more about this area? I'm just reaching out in desperation here, if anybody could offer any advice it'd be greatly appreciated.
