Hey. It's been a year since i've gotten my computer and I want to know if i should upgrade right now. I can go for the x2 4200+ for ~$183, an Audigy 2 with a Logitech Z-5300e speaker system for roughly ~$190, a LCD monitor for around $200, a couple of hard drives (although i still have 40GB of space), or something else that anyone will recommend. Thanks in advance.
