So, i've got a new graphics card, the HD 4850 by powercolor. but i wanted more juice so i got a GeForce GTX 1050 from MSI, the Gaming X one. Now i've been wondering, Will this work? I've seen that the GeForce GTX 1050 runs on PCI-E 3.0, but my motherboard only has 2.0. Will this affect performance? and by how much? Will it be any better then the HD 4850? Please let me know, i have 14 days to return the GTX 1050.
