Advanced CPU, VGA, memory or Mob always cost a fortune but do they really provide equal value to their price? Especially now, the price of RAM gets higher and higher.. How about SSD? I think it should be the best C/P solution for upgrading the old system. You will not have much compatibility problem when using it and it can easily accerate boot, game, page and file reading time. Most people think it is too expensive but that is not correct since SSD is not to replace HDD but to enhance it. To use a small SSD as a system disk and HDD as storage will have dramatic change to system performance. Such as Intel/Kingston/OCZ all have launched small SSD with low price about US$100. With that price, SSD can do much more in improving performance than other components.
