I'm currently researching a new build and have found myself at a crossroads. I need to decide whether an AM3 or 1156 socket is appropriate for my needs. The build will primarily be used for gaming, and will not be upgraded for at least two years. From what I understand socket 1156 will split my pcie bus width when either sata 6gb/s or usb 3.0 are in use. My fear is that this will hamper my graphics card and result in some strange behavior whilst gaming. So, my question is. If i'm in the middle of a game and the hdd begins a read for whatever reason will it cut my gpu down to 8x? If this is the case then i'll most certainly go with the AM3. Any and all answers appreciated. Thank you and have a nice day.
