Today is the release day for AMD’s latest graphics card the Radeon HD 7790. MSI has released their own version of the card. MSI has two versions of the card (R7790-1GD5/OC & R7790-1GD5). Let’s concentrate on the R7790-1GD5/OC because the other one is just the reference design. The R7790-1GD5/OC card is slightly overclocked at 1050MHZ core and has 1GB of GDDR5 running at 6000MHz effective.
