Skyrim blows up my graphics card and the resulting BSOD crashes blow my one of my RAM chips. I first replace the RAM because, like an idiot, I figured when I pull the chip and there's no issues... that must be the problem! But I still get BSOD playing my games afterwards. Must be the video card, then. So I replace the graphics card, and so far, everything is working.
But, lo and behold, I learn my old Radeon HD 5770 performs better than the 6750 I got to replace it. ATI/AMD/Whatever just tossed the same old working into a new package, and slapped a higher number on it.
Moral of the story being: Don't listen to the store employee when he tells you something is 'comparable' to the model you want, but isn't in stock. *sigh*
