Doesn't appear to really help anything. If anything it made it slightly worse.
Steps I took:
1. Tested at Speedtest.net - 7.6mbps download.. .8 mbps upload.. Ping 26
2. Changed the DNS server address to those mentioned.
3. Tested at Speedtest.net - 6.9mbps download.. .7 mbps upload.. Ping 68
4. Rebooted to assure settings took affect.
5. Tested at Speedtest.net - 6.8 mbps download.. .6 mbps upload.. Ping 69
6. Set it to auto detect DNS server.
7. Tested at Speedtest.net - 7.2 mbps download.. .7 mbps upload.. Ping 28
8. Rebooted to assure old settings took affect.
9. Tested at Speedtest.net - 7.6 mbps download.. .8 mbps upload.. Ping 24
After thoroughly testing it, I determined it personally isn't worth it for me. May be different for others, but the result weren't lying.
