GeForce GT 640 Gigabyte OC 2GB Edition compatibility review

Overall, the Nvidia GeForce GT 640 Gigabyte OC 2GB Edition has average performance. This should be expected only from older dedicated graphics cards, so this graphics card should definitely be avoided if building a system to power modern applications and games. This graphics card is now over 7 years old, which means it is extremely out of date and is based on very aged technologies. The level of driver support available from the manufacturer is pretty good, which means new and recent games are being continually optimized.

At this performance level you would be better off getting a CPU with an integrated GPU, because a dedicated graphics card like the Nvidia GeForce GT 640 Gigabyte OC 2GB Edition would not be worth the extra investment, and an integrated solution would be much cheaper, produce less heat, and require less power. We would recommend an Intel Iris GPU on one of the latest Intel Haswell processors, such as the Iris Pro Graphics 5200 Desktop, or one of AMD's latest APU Family graphics solutions such as the Radeon HD 8670D.

With an effective SPU count of 403, the Nvidia GeForce GT 640 Gigabyte OC 2GB Edition processes shading and special graphical effects very well. The GPU is not too power-hungry at 65 Watts.
