Don't buy an ibuypower or Cyberpower pc, same company, same crap garbage components.
Build your own computer buying parts off Newegg (or a local pc store with good prices such as Fryes) - You can spend under $1,000 and run Skyrim on all high at 1920x1080. Main things you need is a GOOD graphics card, processor, RAM, and PSU to power it all.
Processor: i5-2500k, or basically any i7 will work - the i5-2500k is about $199ish or lower
Graphics Card: Radeon HD 6950, Nvidia GTX 560 TI - those 2 are very popular (were the best of the best a two years ago or so) and still are very powerful. The both run for around $200 - 260 - if you dont want to spend that much you could go for a RAdeon HD 6870 or something that is about $100 less, and can still run the game really damn well.
RAM: At least 8GB ram, no less, no more
PSU: At least 650+watts will be needed, especially if your getting a good graphics card
Then you need other components, motherboard, cd drivers, etc. Good luck!
