  We investigate the relationship between the level of a bounded complex over a
commutative ring with respect to the class of Gorenstein projective modules and
other invariants of the complex or ring, such as projective dimension,
Gorenstein projective dimension, and Krull dimension. The results build upon
work done by J. Christensen [6], H. Altmann et al. [1], and Avramov et al. [3]
for levels with respect to the class of finitely generated projective modules.
