Help please! 3 days to figure out why I cant achieve speeds over 70mbps on a 300mbps connection.

Bought an i5-5200 2.2ghz aes-ni processor and 4 gigs of RAM and after a pisspoor installation guide from Nord and digging through many forums figuring out which options do what, I finally got openvpn working without throwing some kind of errors in the log. I tried tcp and udp with the same speeds. it didnt matter I wasn't going to get more than 70mbps on a 300mbps connection. I figured an aes-ni processor would help with the fact openvpn can only use one core at a time and deal with overhead. My options are as follows:

tls-client;
tun-mtu 1500;
tun-mtu-extra 32;
mssfix 1450;
cipher AES-256-CBC;
key-direction 1;
auth SHA512;
auth-retry nointeract;
persist-key;
remote-cert-tls server;
reneg-sec 0;
auth-nocache;
sndbuf 524288;
rcvbuf 524288;
disable-occ
mute-replay-warnings;

Udp fast i/o is checked

Nord disagrees that this box should be able to handle more bandwidth.

Things ive tried:
At least 100 different servers
Multiple connections in a grouped gateway which ironically though may have been a solution for some slowed me down further.

Am I just refusing to believe my hardware limitations? Ive seen people with lesser specs achieve far higher speeds. and I should step down my internet package and save money for bandwidth I can't really use? The bill is about to roll over and Im about to downgrade.
