It's hardly the game's fault that it doesn't run on your old PC. That's like bringing a ride-on lawn mower to a NASCAR race and then blaming NASCAR for your inglorious humiliation.
Made me laugh out loud. My thoughts exactly; My rig is mid to low range on the market right now with a 5770, and it runs Skyrim at about Medium with no hiccups.
I've been pc gaming for years now, and I've learned a valuable lesson to avoid disappointment; Pick up a game, enjoy it, and whenever your next natural PC buy occurs, boot the game up again and marvel at how far it's come.
Case in point; my PC would barely run Half Life 2 when it first came out; I bought the one 3 years ago that came before this one, and had a blast with it. The same is true for Oblivion here; last rig barely, this one fairly well, and the next one should blow it out of the water. Skyrim will be no different.
