I have below the components for what i think equates to a sufficient gaming rig (I also need it to handle high resolution rendering for 3D modelling etc). However I'm a complete novice and I'm trying to learn more about the selection process. Any ideas or corrections are greatly appreciated. I'm kinda out of my depth and I'm sick of paying top dollar for premade PCs that are outdated and useless the next year. Also if you can suggest any other parts that I need in this list please say so. Thanks guys
