95% of this board will recommend VCP
They are right.
But I will offer up an alternative that you can explore for a week with a free trial (just cancel your membership if you do not like it before it charges you)
Card Ladder which is now owned by Collector's (i.e., PSA) is an emerging favorite of mine.
Card Ladder's quickness as well as its user interface and user experience is incredible.
You can get a full list of its features and pricing here (remember, you can start with a free trial)

I am a paid subscriber of both VCP and Card Ladder and do not see them as an exclusive pick one or the other choice. I use both while at card shows and while researching auctions.
