The NVIDIA GeForce GTX 760 2GB is one of the most sold graphics cards today. It has proven to be a great card for those with a 1080p gaming setup as it is relatively affordable and can often be found for around $250. In recent months companies like Gigabyte have begun offering 4GB models of this popular card for an extra $40-50 over the price of the base model with 2GB of memory. Gigabyte currently has the Gigabyte GTX 760 GDDR5-2GB for $259.99 and the Gigabyte GTX760 GDDR5-4GB for $299.99, so they are charging $40 or 15% more to have double the frame buffer.
