I have never been a PC gamer, mainly console. I have a rog ally x and love it especially on my commute. When I hook it up to a monitor though I notice the GPU comes close to 95-98% and the fan is loud. I'd like to upgrade to a full gaming PC or laptop that has more performance than the AllyX for when Im home. Can you recommend a good PC or should I buy a Egpu? Im not looking to spend much more than 1k. Im also not sure technically save, if I buy an Egpu do I need a dock and more accessories?
