I can't speak to gaming (OK for students - real adults should have better things to do, IMHO) but I'd give both of my new acquisitions a good, complete workout before I spent money on something different. You might not find the need to spend the money. I've found it takes a few days up to a couple of weeks use to actually know how well an individual keyboard "suits" me. And I stay in the IBM/Unicomp Model M world because that suits me, and although all are Model Ms, there is enough differences to keep you busy exploring them for quite a while.
Initially, we all are wary of what's new - "it feels funny" - compared to what we are used to. Give each board a real chance before you discard it - and maybe come back to it a bit later and verify your conclusions after more experiece before you send it down the road. But if money is no object and you are curious, do as you will! I think for typing and typing only, you will find the Model M hard to beat, if it is a good one. Because there are different "feels" within the Model M family due to different production periods, and of course due to how "used" it is, your example may or may not let you know if the M is your cup of tea. And my one Unicomp is in my "top 3".
By the way, ClickyKeyboards has good USB adapters, should you need one, as well as extra keys, springs, etc, and the correct nutdriver for Model M cases, should yours need cleaning.
