Thoughts of new PC

..or build as you go along. I run 2 GeForce 550Ti's in SLI mode. but I started out with just one. I would also suggest, perhaps not a TB Hdd, and instead get something a little cheaper, so that you can afford to get a 96GB SSD drive to put your games on. Leave the operating system on the HDD, games on SSD. 8GB of RAM (assuming its ~ 1600MHz RAM speed) should get you moving, yet as MiRai pointed out, your settings may still be on low for 5 accounts, improving your RAM to say... 12 to 16GB of RAM would be ideal.
