Mini Case for 2 Gpu cards

Hi All,

I am going to buy a new desktop pc,

I am thinking to buy mini case: Thermaltake ARMOR A30i with 750W psu

Can it handle two Gpu cards? or is there other recommended case?

I will be glad for recommanded gpu card, I understand that GTX 970 or GTX 980 are the best?

Is there NVIDIA reference cards or its only in Amd cards ?


Thank You
