I have a GTX 970. I've been noticing a performance drop while gaming, been trying to troubleshoot the problem for a while. Low CPU usage in CPU demanding games, low FPS, and 100% GPU utilization even though the power consumption is only 40-50%. I just noticed earlier through GPU-Z that My PCI slot was running @x1. Using 1 out of the 16 lanes available. Well that explained the performance drop.... So I tried re-seating the card. Upon booting back up I was running at x2. Tried re-seating a third time and what do you know, I'm at x4. Do I just keep seating the card over and over until I reach x16? (lulz) But seriously, anyone know what might be going on here other than bad GPU or bad PCI slot?
