Best Graphics Cards for the Money

Last Updated: October 8, 2013

Choosing a graphics card can be a daunting task. This page is designed to make that process a little bit easier providing you with a list of graphics cards broken down into different price groups. The most important factors in choosing a graphics card specifically for data processing is Processing Power (GFLOPS) specifically double precision, the Core Clock Rate and the amount of Memory. The other non-graphics card factors are if your computer has the necessary power supply to be able to run it, available PCI-Express slot and cooling for larger cards such as the AMD Radeon 7990 and NVIDIA GTX TITAN.
