Help deciding a few things overall

[Lucifer02]

Will be buying a ultra-book most-likely with a TB3 port and will buy and eGPU, a monitor. If you guys have any recomendations for eGPU, monitors, hard-drives, keyboards, mouse. Please do let me know. 

For the monitor I'd like something with thin bezels  ( something I can add a second monitor to)

for eGPU ( my gaming load will maximum be battle field 4 an high settings)

keyboards and mouse (I've always used shitty ones so I'd like to upgrade but they don't have to make my wallet empty, so something decent and nice but not too over the top) (would be nice to have a multi-button mouse (like an extra 2-3 buttons))

harddrive (something good which will last for long around 500GB)
