I usually take in less than 2000 calories a day at 170lbs and my performance hasn't really suffered greatly from it, but I wonder if there's a need to take in more calories to really make gains or is the number of calories I take in irrelevant
It's quite easy to get a reasonably accurate estimate of daily energy and macronutrient requirements with a few simple calculations -
1: Go here
to calculate total kcals/day.
2: Calculate your protein requirement 1.2 - 1.8g/kg/day.
3: Calculate carbs 6 - 10g/kg/day (Note: this varies depending on training intensity and duration so the more active you are the more carbs you need.)
4: Total kcals/day - (PRO + CHO kcals) = fat kcals/day (divide by 9 to get g/day).
Any book on sports nutrition can provide a more detailed explanation of the math if you're interested in learning more.
