To over-simplify things: The grinder makes the flavours/aromas from the roasted beans available. The espresso machine pushes hot water through the grounded coffee to transfer them to water.
A better espresso machine will allow you to improve / add consistency in this latter step. Hence, a GS/3 paired with a
basic grinder should consistently provide you with a
basic espresso cup quality.
Doing the reverse, upgrading your grinder (for example to a Baratza Vario, found to provide a comparable grind quality to Titan grinder, while not being built as one; or straight to a Titan league grinder) and keeping your current espresso machine would usually, but may be not consistently, provide you with a better cup quality.
Keep in mind that an E61 HX is already good equipment (even if I don't know the exact model you have). Upgrading to a GS/3 will buy you functionality and convenience but could be found to provide only a slight improvement in cup quality.
Also, the grinder and espresso machine can only express what was in the bean originally. Good roasted beans, along with good technique, are probably more important than the espresso machine, especially if you already own an E61 HX.

I dare not giving you a direct answer... ;o)
