>Or is single-core CPU and DDR just so outdated that it's hopeless?
yes, especially since you dont even have good ddr or a good cpu from when they were new
>Also the BIOS has a setting for AGP(yeah it's 4X AGP :() aperture max is 256MB does that mean I'm only getting half of the video memory??
agp should be 8x (maybe your card/motherboard is terrible), and aperture is system ram that can be shared with the card
>Also I try and defragment my drives cause I think it always slows down when it's accessing files, but it always goes for like 10 minutes and says "some files could not be defragmented" and gives up.
hard drives are the worst bottleneck in any computer using them (even with a solidstate drive). if you have a decent defragger and enough free space for it to work properly, then its probably not going to get much better.
your comp isnt a total piece of crap but it sounds like its barely meeting minimum requirements or something (at least for newer games).
