I found a small notebook I want with a Intel Core 2 Solo Processor SU3500. My confusion is whether it is a 32Bit or 64Bit processor. Different sites I've looked at says it "supports" 64Bit processing. The OS that comes with it is XP Pro, not the 64Bit Edition. I would prefer using a 32Bit processor because of some of my older XP programs. Any info on this would be greatly appreciated.
