Those should be fine for edge routers. You wouldn't want to bring in the whole internet routing table from the ISP with that amount of memory though, but a default route inbound from the ISP and advertising the networks that the customer owns should be fine.
According to this on Cisco's site, you only need about 512Mb...I would've thought it would be a lot more. You can have the ISP send you just a default route also though. Depending on the type of attack, you may need to get the ISP involved to block traffic. If you have 300Mb of traffic coming in from an attack and you only have a 20Mb internet connection, then you can see that it would easily overwhelm you. The router could probably still handle it, but your internet connection would be useless. Control plane policing is good for anything directed at your router like DoS attacks, etc.
