Steam/Origin can saturate those, I usually hit 30 MB/s from them. Uplay used to but for some reason for the past 2-3 weeks uplay always downloads at half my actual rate, not sure whats going on there. At least the only thing I download on uplay are updates for siege, so its only a concern once every 1.5 months
I don't think ASF is gonna hit 30MB/s idling.
You don't actually play games... do you?!?!
