I have to agree with everyone on this question.
Lets say that you do find a mobo/CPU, RAM, HD, DVD RW, video card, and sound card to upgrade this system. You have nearly all the parts for a new system: just the case, and OS.
Personally, if you are not going to out-tweak the new computer much, you can go with a pre-built system and re-use your keyboard, mouse, and monitor. You could then link both of the computers together via a KVM switch, and you will have the best of both worlds
A KVM switch allows 2 computers to share a K
ideo(monitor) and M
ouse. The last time I checked you can get a decent one for under $70
We are all curious like a cat. We wonder, we ask, we learn.
Please post back when a suggestion works, so that others may learn.
