Changing Win XP to 7

[Raiyushi]

So your basicly saying that 32 bit OS's cant adress large amounts of RAM, about over 4 GB.

Im thinking of doing a similar sort of thing actually. I have XP Profesh.

4GB RAM
AMD Phenom 9750 Quad Core Processor 2.40 GHz a core.
NVIDIA GeForce 9800 GT 512 MB video card.

Should I upgrade? I will probably get the 64-bit OS because im thinking of upgrading my RAM.

Also, doesnt' the 16, 32, 64 bit change the color quality? Right click the desktop, propities, it says color quility (32 bit) on mine.

Yeah. 16-bit is 65536. Which means you can display 65,536 colours because it's 16-bits. 32-bits is quite a bit more. However, you can never truly find TRUE 32-bit...Most you'll probably get is 24-bit (16777216) or so. However, most of these colours are achieved via Dithering anyways so if you sometimes notice that if you go 16-bit and the colours are off, but the image is crisp, then going 24-bit or 32-bit causes the image to go off a bit and the colours are better but seem washed out... It's because your monitor is dithering (Mixing 2 colours to make 1 colour)
