If the graphics card is built into the motherboard, it's using 64 MB of memory from your running memory, but I'm not sure if that's the problem anymore. 68 MB isn't really enough to slow down your computer to much, and 512 MB of memory should run Windows XP just fine, unless you've got several programs running at once.
On my old computer, I had Windows XP SP2 and after I upgraded to SP3 a few of my games preformed poorly. At first I didn't think it was SP3 that was causing my games to be slow, but after I uninstalled it, my games were running smoothly again. I also read on several other forums that people who install SP3 often noticed slowdowns in their games. Once again it's just a theory and I don't advise uninstalling SP3 unless you know what you're doing.
The Specs of my old computer were:
Processor – AMD Athlon 2x 2.21 ghz.
Memory – 2 gigabytes of DDR memory
Graphics – ATI HD 4670 series graphics card with 1 gigabyte of memory
I've never bought a laptop, but someone told me that Asus brand laptops are good for gaming (the batteries supposedly didn't last to long on them) and Alienware is also a good brand for gaming (If you can afford it that is).
