Hi! I’m Ali Tauseef, and I have been writing for Tech4Gamers since 2022. I love all things computer hardware but am particularly fond of CPUs and motherboards, and I like to stay up-to-date about the latest advancements in these worlds, and when possible, write about it. When I’m not doing that, I like to get into a little FPS action in CS2 or get lost in the vast world of RDR2.
