Bournemouth splashed a club record £10million to secure the services of Afobe from Wolverhampton Wanderers last week and the striker made an instant impact at the Vitality Stadium, scoring his first goal in the 3-0 victory over Norwich City on Saturday, in just his second appearance in a Cherries shirt.
Arter was left impressed by Afobe's performance and stated that the former Arsenal youngster's arrival has lifted the excitement level among the Bournemouth fans.
Arter said: "He looks at home in the Premier League.
"I thought his hold up play was terrific. Benik offers pace and power and that is probably why the manager wanted him so much.
"You always want to sign good players and bring in any new players there is a sense of excitement for the crowd. He showed why we wanted him so bad.
"As a group we're not putting any pressure on Benik. For every player, no matter what your price tag, you put pressure on yourself.
"So it is nice for him to get that monkey off his back."
