I have an Athlon 64 X2 (W) 4600+ 2.4 GHz processor, with Windows XP 32-bit. I have read that the AMD 64, is actually a backwards compatible (32/64) processor, so you can run either Windows 32-bit or 64-bit if you want.
When I go into my system information, it reads: Processor x86 Family 15 Model 75 Stepping 2 AuthenticAMD ~2405 MHz
It says it is a 32-bit. So do I have a 32-bit or 64-bit processor? And can I upgrade to Windows 7 64-bit?
