[QUOTE="IvanLasston, post: 1192457, member: 145676"] 64 bit actually degrades performance in some cases. The key here is programs can access more RAM, but the cost is the address decoding of that extra RAM. I have found in most cases 64 bit applications tend to run slower than 32 bit applications for programs/data that fit in a 32 bit space. This is also why I asked the question - to see any performance gain you need more than 4GB of RAM, a 64 bit OS, data that is greater that 4GB, and programs that can address 64 bit. If any one of those is missing then you will probably see performance degrade. Think of it like this - putting 91 octane into your car does not make sense unless your engine can take advantage of it (high compression, turbos, etc) every day cars it is a waste of money. Another metaphor, trying to run faster by putting on bigger shoes. I.E. I now have size 14 instead of size 12. 14 > 12 so I must be getting some performance. [/QUOTE]
