Hi, I have an Intel Core 2 Quad CPU @ 2.40GHz (4CPUs). Which is 64 bits. My current version of Vista is the 32-bit Home Premium version. I ordered the Windows 7 Home Premium Upgrade. Will it give me the option to install the 32-bit AND 64-bit versions? Or did I perhaps order the wrong one? And if it is optional and I installed the 64-bit version, would it run slower than the 32-bit version? RAM: 3GB Video Card: GeForce 7350 LE (128mb video Memory)
You will be able to install either, but if you install the 64 bit version, you'll have to do a fresh install. Your computer will actually run better with the 64 bit version, but make sure that you have 64 bit drivers for all your hardware.
