hi I have a questions. I'm building a new computer with a ga-ep45 ud3p board. Intel e5200 cpu using ddr2 memory 4 gb, 500gb hard drive I want to go to windows 7 witch 32 or 64 bit what is better.
Use 64-bit. With a 32-bit OS you will be limited to a maximum of 4GB of total system memory, which includes both RAM and video memory. If you have a 512MB Graphics card, you would be limited to 3.5GB of RAM usable in 32-bit. A 1GB Graphics card and it would only be 3GB.
