yes but it may drop below 150 fps,
I was rolling an i5 2400 with a 650ti, with 4:3 1280x1024, Solid 150 fps so it did keep with the 144hz, it would dip here and there tho.
Now I have a 1060 with an i5 3570k and happily get over 250 fps.
Yes, GTX 650ti 2GB does support 144hz.
lul how can you have a 144hz monitor and a 2gb 650?
how the fuck do you want to play 144fps with 650ti L M A O
