I am a complete noob when it comes to GPUs and I need help choosing one for my first PC Build. I will be using a Dell u2414h IPS monitor, and have budgeted my GPU to under £150. I would like t know which one , the Sapphire R9 270x or the R9 280 is better. (The 280 has 3GB and The 270X has 2GB, but a 1GHZ base clock.) Please help. I am not en expert in this area. Maybe it is worth considering a GeForce for the same price if it has more performance in terms of FPS.
