Hello, I am planning to upgrade to asus SABERTOOTH 990FX R2.0 motherboard. Sorry because I am not so tech savvy so I may not use the proper technical terms. Just a general question, how good it is overall?? I also have an existing sapphire R9 290X graphic card which is as any one may know quite big. So in future I am planning to also add asus Xonar Essence STX sound card to this board. Again any inputs on this of how good it is? So as everyone knows that since both pci slots are close my hardware engineer told me there can either be a heating problem or else the sound card may not fit in the small slot due to the large size graphic card. So in that case we will have to move the graphics card to another pci express slot which means it will give lower performance. So now my main question is will moving the graphic card to say the second pci express slot degrade its performance or is it just a myth? If yes then how much slower will the card be, because I use my pc mainy for gaming? Thanks to all.
