The i7-9700 might bottleneck it a bit at 1080p, but at 1440p performance should be good, especially at racing games.

I was just looking at this gpu. So then $300 is a good price for that 6750?? My son mainly plays online games like Fortnite and some other racing game. It would be paired with an i7 9770 cpu if that matters.
