I actually bought that card a long time ago at an NCIX warehouse sale. It very well may have been an open box item but ncix had so many of them which made me think they were just clearing old stock. It wasn't that much cheaper than regular price too.
Anyways, I never actually used the card...
It's not the RAM. I'm 99% sure it's the hard drive. Get an SSD to boot your OS in and keep your 1TB for storage. If you go into task manager, you can see how much RAM you're actually using and unless it's showing that you're always using close to 4GB RAM, you won't really need to add any ram.
Was also going to suggest that. After blowing 1600 on a 55" Smart TV (this was a while back), I would spend a bit more for a projector and a screen if I could do it over again.
