The window tearing could be a vsync issue - use raven and "disable unredirect" - reboot and see if that fixes the tearing. Other than that - its probably due to the software rendering of the elderly graphics chip. The card you have selected is an AMD model - its an older model around 2010 vintage - so much better than your current 13-15 year old model. AMD itself does not support this older model - the opensource community through its nouveau drivers does - but I don't myself have any experience with AMD to say whether its a good or bad support.
