Recently I have made the jump to 64bit. Originally I was on 64bit Vista but I found it almost impossible to find any software and installing everything turned into a nightmare so I just gave up. I have now been on 64bit Xp for a few months and have to the conclusion it really isn't that special. I literally have 4 native things installed in 64bit and everything else is in the Program Files (x86) folder! In terms of performance I have seen no great gain. If anything its running worse, with it being a bitch to start up and certain applications it just doesnt like. There is no decent anti virus or firewall version either so I end up with a hacked up solution. all in all im not impressed. There does not seem to be enough wide spread support for it so its being held back. I for one am seriously thinking of going back to my version of heavily tweaked Xp 32bit, which ran like a dream! What has everyone else's experiences been?
