Hello there, Thank you very much for reaching out to us. I'm sorry to hear that you are having issues with stability in the game since you've upgraded to this new GPU. If you haven't already, we'd also recommend ensuring that Windows is fully up-to-date. Assuming that you've probably done this already and the issue still persists, while we may not have an immediate solution to offer, to help us further investigate any underlying issues that may be occurring, we'd kindly ask for a copy of your DxDiag. You can paste it on [url=http://www.pastebin.com]PasteBin[/url] and provide us with a link to it when completed.
