I have a question about vista. I just bought a new pc from a friend. It’s a custom built Intel q6600, 4 gig ram, SAPPHIRE 4870 with no operating system. Being a college student I can download a free copy of Vista Ultimate 32 bit from my university. I have had a few people tell me vista 64 bit is better. Is it worth the $100 for home premium 64 bit over a free copy of Vista Ultimate 32 bit?
