Well if you use XP (unless it's Pro x64 Edition), 8GB will be useless to you because it is a 32-bit OS and thus will not detect more than about 3.5GB.
XP Pro x64 Edition is 64-bit and detects up to 128GB, but you likely only have a 32-bit XP which only detects up to 3.5GB.
Is There big difference between 4gb ram and 8gb ram?
Im a gamer and i use Windows XP
What if i change windows i just wonder if extra 4GB is gonna make big difference
