Whats the max speed V1 and V2 can go?

i have the 1000/200 speed and waiting for 10gig to come but iam not sure to buy deco xe200 or xe75 for little faster wifi speed, i only need cabled 10gig for office room and thats enough for me, no need to go faster than 1gig cabled for house products, if V2 is fast enough i want it in every room for its rent price its perfect.

Thank you
