My new editing laptop just came and in line with discussions here I choose NOT to go 64 bit and got just 2gb RAM. Set up machine and it IS 64 bit so I ask how will 64-bit and 2 gb do for Vegas or must I go now to 4GB to get some mileage from the 64 bit. The 64 bit is more expensive than what I paid for so I don't see returning it a good idea.
