i have a MS-7636 H55M-E21 an Intel core i5 CPU 650 @ 3.2 Ghz (4 CPUs). I think it has 1PCI express gen2x16 slot 2 PCI express gen2x1 slots and 1 PCI slot supports 3.3V/5V PCI bus interface. I don't know what any of this means or if any of those slots that are supposed to be on my mother board have anything in them. It has a Intel HD graphics(core i5). I'm thinking of getting a new graphics card for up to $200. Any suggestions would be great since i have no idea.
