How to Seperate Games from Browsing with Dual ISP

[pixfour]

Hello,

I'm trying to do a multi wan setup that would seperate games from browsing. I would like to load all game traffic to WAN1 and all browsing to WAN2.
For Example:
WAN1 = allow all ports
WAN2 = ports 80 and 443

Please if any one did this kind of setup I would be very thankful. I already did some research but I cant find tutorial similar to my scenario.

Thank You in advance.
