The most common misconseption about 64-bit is that people thing "Hey its 64 bit! That means it rund 2 times as fast as 32-bit!" Well there wrong. In my experience, applications run at about 150% on 64bit, and for a designer like myself, thats a prity good jump. Todays games wont do much beter, but once they come out with ones in 64bit, I expect to see a huge jump in quality.
