Does the dynamic contrast ratio make a huge difference (Asus vs Dell) and will the 5ms to 2ms be very noticable (Asus vs Asus)? I will mainly be using this for games. Would you recommend another around this price point? But has to be 1080p.

I prefer ASUS display, and 5ms-2ms diference will be very negligible, you wont even notice.
