For several months I used my Core 2 Duo installed on a DG33BF Intel desktop board and 4 GB of RAM with 4 HDDs adding up to 1.3 TB. Everything built on a big CASE appropriately ventilated and a Top of the line Power Supply. Things couldn?t have gone better. I use my system for data backups of my customers, encoding or transcoding video files, editing high resolution pictures and running a few virtual machines for testing purposes. I would normally be pushing files to the network, watching high resolution mkv files, and of course browsing through the internet. Several times through the last couple of years I have tried and ?re-tried? 64 bit editions of windows. However the last time I tried still many things keep me awake thinking about when will 64 bit computing finally take off. As of May 2008, I just tried the latest Windows x64 Vista Ultimate w SP1. The performance of my system decreased dramatically even though I tried to download all the latest drivers available. Not that I have many weird devices? Many applications from Microsoft even though downloaded for x64 run in 32 bit mode. Example of that is the virtual PC. When running an installation the system could not get slower, when virtual pc machine # 2 turns on the same thing happens? I could say that the only advantage is that I finally get to ?see? my 4 GB of RAM instead of the 3.23 GB win 32 bit shows. I guess that for the fifth time I will roll back to 32 bit computing hoping many more users give the appropriate feedback so that we will finally enter the x64 era? or will it even be necessary? No performance gain yet anyway.
