I was thinkink 400$ for router+switch and a dual band AP. As a matter of fact I already have bought the amazing CCR with Tilera cores for my office and it's a beast for a small business even a medium one. Carrier grade router.
Budget is not so much of a problem. But I am not willing to pay 1000$ for a home use setup.
Both gr3 and hp ac can do Gugabit routing without problems. It has been benchmarked by many users. They both circle around values like 850Mbps-950Mbps on WAN with no issues. Problem is what resources are left while routing such numbers. Another problem is the PPPoE encapsulation needed because that's how my ISP delivers a fiber optic connection. This adds an extra layer on the TCP/IP stack and that's where most entry level Mikrotick routers reach the limit. Also the Gigabit speed is a huge factor of course. Yes 500Mbps would work even with PPPoE on those 2 routers.
Also looking at throughoutput of each router in the tech specs does not help much. They are not tested with PPPoE. Of course..one can extrapolate but...
The RB3011 would fit this but as stated early by p1chl it is kind of a failed product being the first one on which Mikrotick decided to use ARM.
RB1100 would also fit. But it has features that are of no use to me in this case like PoE, redundant power (so fans - noise) microSD storage and so on. Yeah..its place is in a rack not on a desktop. What I would like is a passive cooled one on a desktop but with those specs more or less
