Replying to SNOW on MAC w parallells?

has anyone tried snow on mac using parallells? I just downloaded it and I am now running win 7 on my mac. but I dont know if it will work. Just dont think I'll use that amount of money on a game I'm not sure will even work.
My mac isnt the best but it is running with a quad core i5 and 8gb ram.

I used parallells because I didnt have an external hardrive or a CD disc.

oh and if you dont know what parallells is, it's a way of running any windows as an app. so you dont have to split up your hard drive and formate it as a FAT system.
