I was thinking about buying a Nvidia GTX 570 and I was wondering if it would be a problem for my motherboard since the current graphics card I have in it is a radeon hd 5770 and i think has a standard pci express 16 times not 2.0. So will the new graphics card cause me problems compatibility wise?
The GTX will fit in that slot. your HD 5770 is the same just as the GTX 570 is. The question is what size and brand is your PSU (power supply)? and does it have the 6 pin coming off of it because the GTX need a power source. If you go here to both the sites they will give more info.
