Never built my own PC before from the ground up. Does this PC have any useful gaming components?

This old Lenovo I found in a shop. The processor was what I mainly wanted it for and it was only $100 since it needed a hard drive and was slightly outdated.

What parts of this PC would be good for gaming+ live streaming at the same time? Also, ignore the Vista as standard OS. I have Windows 7 64 bit waiting in the mail.

I'm gonna get 8GB RAM when I get a bit of money in the bank again as well.

If the processors is Quad Core (4 Cores) and runs on above 3.0 GHz, then you can buy the processor. It will be nice gaming processor. As for RAM 8 GB is OK to run games. You have to buy a nice GPU something like 1 GB DDR5 with 128 bits of Interface or 192 bits of nterface. Don't go with DDR3 Graphics Card because they are outdated.

RAM and CPU are above average but not exciting…
GPU isn't powerful for up-to-date games…
GREAT GREAT GREAT value for money
