Okay first the Toxic test was made with a higher version of cataclyst 13.5 ! vs 13.11 on the hawk.
________________Toxic:_______________________Hawk:

3D Mark Firestrike _2991________________________3092<- Winner
Unigine Heaven____2237________________________2375<- Winner

So if it is 2Gb Toxic vs 2 Gb Msi gaming, then take the Toxic
but if it is a 2Gb Toxic vs 2 Gb Msi Hawk, then take the Hawk
The Hawk has the older Cataclyst in the tests and still wins in most of them.
