Hello, i have a Power Mac G4 Cube, upgraded to G4 1,2 GHz, 1,5 GB RAM and to GeForce 6200 graphics card. The results from the GPU upgrade are not so noticeable. It shows enough speed increase in OS X Leopard (desktop window opening, web browser etc), but not at all in video media playing. I wonder if this happens because of the G4 speed. Would it be a significant change in display results, if i install another CPU accelerator? For example, a G4 1,6 or 1,8 GHz? There is an accelerator G4 card for sale, but i want to be sure if this could make a difference combined with the GeForce 6200 or it would be a waste of money. To be more specific, i'd like it to display videos in about 900 x 700 or maybe more resolution and in a format other than mkv. If some of you made a similar upgrade to your G4 Cube and see results in video media displaying, your answers would help me a lot! Thank you in advance!
