AMD Radeon HD 7970 shows as FirePro D700 in 10.9 Mavericks

[comatron]

yo guys. i jsut set up my hackintosh with 10.9.4 and clover bootloader. i am confused as **** because i have NO DSDT and clover isn´t set to inject AMD gfx cards. my 7970 3GB works OOTB. is that usual? the UI seems a bit laggy sometimes (maybe usual with a 2650x1600 and a 1920x1080 screen) but i tested 3D in some game and that worked.

also did a cinebench test now. what you say?
