I recently did a clean install of Vista Home Premium on my new CPU that I just put together. I have a qx6700 quad core processor, EVGA 680i SLI MB, 4GB of PC6400 Corsair ram, and a Nvidia 8800GTX video card. Because of the 32 bit memory restriction, Vista is only seeing 2.8 GB of my ram along with the video ram. I understand that the 64 bit version will see all of the ram. Is it worthwhile going with the 64 bit version for this reason? Are there other reasons that the 64 bit version is better than the 32bit version? How difficult is it to convert from 32 bit to 64 bit? Except for needing the 64 bit drivers for the hardware, are there any other roadblocks?
I know it's a lot of questions. Any help appreciated. Thanks in advance.
