Hi! I'm new to this forum thingy, I just wanted to ask if I have a MSI 790GX-G65, and it is AMD/Ati supported, can I put a Nvidia GPU to it and have no problem with performance, drivers (I only want to use one Nvidia card)(I have a AMD CPU and AMD Radeon HD 6700 Series graphics card at the moment) but my old graphics card is only 1GB and its getting...old... so I was looking tought the sites searching for a new video card and there are some cool Nvidia cards. As you can see I know nothing about these stuffs, so I need your help!
