Was your whole plan about having a family in your 20s? If not, then I don’t see how the lack of a significant other matters. What career plans do you have? What interests do you have? Also, keep in mind that validation should come from within, you shouldn’t let anyone (or their absence) define how you feel about yourself.
The first one I got was some integrated cirrus logics chip that didn’t even have 3d acceleration. The first one I bought with my own money was a GeForce 7800GT in late 2005
