Last week i switched from a 5 year old 350 atlon xp 32bit to windows 7 I-3 dual core 64bit cause my workhorse finally went black.We were recording a bass track and i heard a zzzzit and that was the end of last saturdy night. The new computer is great, no driver issues with any of my plugs or the zed R16 driver and i did the usual tweaks. Disabled all non relative services. Nothing loading on statup. Never sleep,never turn off,no screen saver. No retore points,just one backup image. No security and no "do you want to allow this program"promt.(that one really bugs me). My questions: Am i missing any,is windows 7 different in optimizing performance. and What's the gain with 64 bit as opposed to 32 ..what's it do? run quicker,more efficent,make better use of the ram? and Single core,dual core..some macs have 8 cores, how many cores should i have to preserve my manhood?lol..What do they do? Thanks for reading.
