I paid $1500. It looks nice. Seems to play games nice. But someone told me that a certain part in it is old and no longer any good. I don't remember what part he said it was though. Unfortunately I have no way of knowing what's in my computer. The builder told me he used all new parts though. I tried contacting the seller about what was installed but he says he doesn't remember and has no way of finding out what all the parts were. Could I have gotten ripped off? How do I find out what I have installed? And is what I have worth the $1500? Better yet will it last me a good 3 to 5 years if something in it is already old?
