Ok all, I did some searching and have not found anything specific to this, but I have not take the plunge to 64 bit OS in any fashion for home use and was hoping for some help. I just built me a new rig (Core 2 Duo Quad Core CPU, 4GB RAM, nForce 8600 GT 512MB x2, SATA DVD Burner, Seagate 500GB SATA HDD x2) running Vista Ultimate 32 bit currently. Now, I am a gamer (mostly play WoW, Neverwinter Nights 2, FEAR and a few other games) so I was wondering how well games overall work with 64 bit. I know that most all my productivity applications work well on 64. Big question, will I really see a diff? I use 64 OS's on my servers here, but they are work horses (4 dual cores, 16-64GB RAM and Local/SAN storage out the wazoo) and know it's great, but I never looked at it from a home perspective. What are some of the pitfalls that I might run into trying out a 64 bit OS? Thanks!
