You can get a pretty decent graphics card now-a-days for around $300. Well wroth it!!
I managed to make a big jump! went from the GTX 970 to the 1080Ti! had to change the motherboard out and all that. I think my PC is now future proof... for a while I guess. Spent like close to $700, a local shop nearby my house was doing some kind of special. but thats what I got! now I'm ready to get the game! ... next paycheck after 2 more bills to pay. hahah!
