I haven't heard of anyone getting 2560x1440 @ 120 Hz with that adapter. It can only handle around 100 Hz with 18-bit color (6 bpc). 1920x1080 @ 144 Hz is still under 330 MHz, so that wouldn't affect 144 Hz monitors.

That's weird because the 330 MHz dual-link DVI limit shouldn't affect DisplayPort with an active adapter unless AMD changed something recently. Other people have used that adapter with AMD cards, so I don't know why you're seeing this limit. The limit should be 360 MHz with 24-bit color (8 bpc) and 480 MHz with 18-bit color (6 bpc). Is the limit actually 330 MHz, or is it something else like 327 MHz or 360 MHz?
