I have a late 2004 dual 2.0 PPC , running with 7 GB ram, with a GeForce FX 5200 video card, "original" which I fear is on its way out. Looking for a replacement which might be a little bit better. I am not a gamer, but dabble a little bit in photography and some low end graphics like Hash Animation, and some photoshop. Went to a local mac store which has been around since late 80's and they say there is nothing out there, please tell me they are wrong. Any suggestions will be appreciated.
