[QUOTE=IWorx-Paul;12488]Will you see significant improvement over 32 bit? That’s probably up for debate, I don’t have the answer.[/QUOTE]The way I look at it, if you have a 64 bit CPU why not use a 64 bit OS. I mean worse case scenario you are running at the same speed as 32 bit and I dont think price is really an issue anymore and as more and more programs are written for 64 bit the future looks bright (wow that was cheasy )
