I've got two computer offers, one of them has a better graphics card from what i've seen on comparison sites (SAPPHIRE HD 7850 2GB OC GDDR5) and the other is a geforce GTX 650 Ti (which has cuda cores)

I need the computer for 3d work (modelling, rendering, animation, all that stuff), which one should i prefer?
