AMD Radeon HD 6790 Review

Today we have an interesting card for review, the Radeon HD 6790. Read full review
Like most high performance cards, the Radeon card takes place of two PCI slots, but uses one PCI express slot.

The reason why I like the card is that it delivers great performance and also a great price tag. If you are fan of Nvidia video cards, then GeForce GTX 460 will give you about the same performance and about the same price, but Nvidia plans to discontinue this card, so if you will decide to get it, hurry up. Coming back to Radeon, let’s see the official specifications of the card:

AMD Radeon HD 6790 Review

Anyways, as you can see, there is nothing really special in the spec section. The price of the video card is about $150. I personally never spend more than $200 on a video card. I am not a fan of buying brand new models because in a couple months the price may be reduced by about %50.

When testing the card with Crysis 2 game, I find out that GeForce GTX 460 beats the Radeon HD 6790 by good amount of frames per second.
For Radeon I got 64 frames per second and for
GeForce GTX 460 I got 73 frames per second.

In my opinion, if you can get GeForce for the same price, go for the GeForce, unless you are ready to die for the Radeon HD 6790
