My graphics card is PCI and has 256mb. 512mb 100gb for the machine. I'm not going to upgrade me graphics card until theres PCI 512mb. I was wondering whats the next best thing to upgrade other than a graphics card?

put another 512 mb RAM module in you computer !! (or a size that you can afford, etc.)

I would say memory, then video card. There is a big difference between 512mb and 1024mb or RAM. Just make sure that you are using the correct types as some motherboards can be quite picky. If you list your motherboard model (this can be found out by running this (http://www.cpuid.com/download/cpu-z-140.zip) and opening the cpuz.exe file and then looking under mainboard).
