My sister has an OEM computer from gateway, which has an older i7 cpu, and 8gb ram. We installed a 7870 XT for the graphics card, and it runs Tomb Raider nicely at 60fps w/ tressfx on and normal everything except for ultra on textures. However, the temp has gone up to 90C the highest...it usually lingers around 80C. I can't imagine that high of a temp is good...the metal around the case gets pretty hot. Would the gpu burn out prematurely because of the high temperature? Oh, and it's not overclocked or anything.
