Hello I'm new to computers or at least the internals. I was looking to upgrading my GPU but I'm concerned it will cause a bottleneck somewhere else. I bought a rig for $100 and it came with a Core I7 quad core 920 @ 2.67GHz, 12GB of DDR3 1067MHz ram in 3 sticks, and a GeForce GTX 650. I'm thinking of upgrading to a GTX 1050 but not sure if its the right move to get more performance out of my machine. Any and all help would be appreciated.
