You're completely wrong about me. I have a 4 year old 2nd hand CPU, motherboard and RAM, 5 year old Korean monitor, and a 1080 that I bought on launch after saving £20pm for 2 years. Some people highly value quality and longevity.
You can get high value and longevity from much cheaper keyboards, if you can get Cherry MX switches you are already half way there, keyboards with those switches start at £40, if you want RGB then add another £20-£40, basically you can get a great keyboard for £100 with everything you could possibly need, the only reason this keyboard is £240 is for the gimmicky cloud feature that you'll use once then forget about.
BTW what monitor have you got? Many of those 1440p korean monitors could overclock over 100hz, had a DGM myself, it was great.
