Your wireless speeds will vary greatly from device to device. Different WiFi cards and hardware, etc. will all perform differently, and you'll probably also notice different performance on tests around different parts of the house. Now will you actually notice anything bad without looking for it? Probably not with that speed.
Working and play both don't depend heavily on speed -- download speed only matters when actually downloading large files, and on top of that, many sites out there won't push 1GB full data to you anyway (they'll throttle your download on their end). Upload isn't meaningful to most people with normal use cases. Could you move down in speed? Likely, but there's a cost/perfomance ratio component. Example, is it really worth it to you to save $10/mo. to go down to 200mb/s versus just staying at 1gb and never having to think about it again? Thats more for your to personally decide based on your needs.
What you'll want most out of both situations is network stability, which is the strength LAN/wired provides. Ethernet eliminates the instability of wireless, which is what causes things commonly perceived by people as "lag". Lag = a ping/connectivity spike, or prolonged spikes. Good routers and good connections still help here even our wireless, but they won't defeat the consistency of wired.
