Hey I have a Performa 6200CD with 64mb RAM and a 20gb HD partitioned into 2 partitions. Currently it has 7.6.1 and feels extremely buggy. I know this computer is a road apple and all that , but I'm just wondering, what OS should I install? I have install discs for 7.6, 8.1, and 9.1... Well I'd just like some advice in which I can get the most out of this machine, in usefulness and in speed. Thanks!
