Can't you swap the keycaps from the original board with the Gateron switches? There is a significant difference between Gateron switches and Cherry switches. With that said, the keycap can have a very real difference on your typing experience. Are the caps you are describing stock out of the box or are they actaul DSA keybaps. Vortex makes some outstanding keycaps, especially on their Poker keyboards. Are the DSA's you referring to really DSA or maybe OEM profile?
I have come to prefer Cherry switches over Gateron. They are more consistent and have just a little more resistance at the bottom of the keystroke.
