With the sub-arcsecond resolution of Chandra, a strong association between low-mass X-ray binaries (LMXBs) and globular clusters (GCs) has been established in early-type galaxies (20--70% of LMXBs reside in GCs). Most of this association has been based on GC lists generated from ground-based observations, which can not resolve GCs at Virgo, or HST-WFPC2 observations, which have small field-of-views. With the HST ACS Virgo Cluster Survey (VCS), a uniform sample of the GCs in the central 3' X 3' of 100 early-type galaxies has been created that contains not only positions and magnitudes, but also structural parameters. We present results of a study using this superior list of GCs and archival Chandra observations of LMXBS in a sub-sample of the HST ACS VCS to probe aspects of the LMXB-GC connection.
