...If your system meets the minimum system requirements then your CPU speed and RAM are the factors that impose limits on the complexity of your projects.
Generally, the faster your CPU is the more instruments you will be able to play simultaneously and/or the more effects you will be able to use. The more RAM (memory) you have the larger and more samples you will be able to load and play back smoothly.
