OWC Mercury Accelsior and bootcamp

Hi guys!
I have a 2012 Mac Pro and today my ssd died.
I use mainly Windows (because of 3dsmax) so I installed it on the SSD.

If I get a pci-e "OWC Mercury Accelsior" will I feel a HUGE difference? I'm asking because, since I'm Brazil and the taxes here are ridiculous, I'll pay almost 3 times the price of a normal SSD (like Samsung's).
Remembering that I'll be using it as the Windows partition.

Thanks!
