VirtualDJ - Mac user Numark V7 problems

Home userMember since 2011

Trying out this program with the trial and having latency problems when used in conjunction with my Numark V7's. Especially when video djing which is the reason I might purchase. I turn off airport and everything which helps and have auto-latency turned on but still have bad giltchy/digital sound when scratching. Video djing also lags and glitches if you scratch too fast or do too many commands quickly. Below are my specs, I might get a better laptop if they aren't up to par but I can't see why the computer wouldn't be powerful enough since the CPU usage bar on the program interface never even really gets past 50%. If the computer isn't up to par, do you know which Mac specs would do the job?
