Hi there, i currently have windows vista ultimate 32 bit x86 but i'm thinking of upgrading to 64 bit ultimate but is it worth it? Any advantages? I'm sure you get asked this a lot but just wondering if it's worth it. PC Spec: AMD AM2 6000+ dual core processor Asus m2n-sli deluxe mobo 4gb ddr2 667 ram asus x1550 graphics card 1gb Any help appreciated! Thanks.
