All I know, is the specs will be above mine. So sadly I don't think I will be able to play it. My guess, as was said before, 4 gigs of ram, 2.5 ghz dual core processor. Maybe a bit more. I don't know what the latest graphic cards are, but I will say yoiu will need the graphic card that will be released in the Summer to get the max effects.
To say if your PC runs New Vegas will run Skyrim is not correct. Maybe, MAYBE, minimum spec will be what the recomended specs for NV, but I believe the specs will be quite more. Also I believe people will want the amazing pics we are seeing. I am not sure
it the pics shown are 360 or PC pics, but people will want them, so I am will even say a dual core minimum 3.0 ghz. and the high end graphic cards what are out now. I won't be surprised if the high end cards out now, will only play the game on medium specs and people will have to buy the latest graphic card that comes out in the summer or fall.
The game needs to run on Xbox and PS3 hardware, which is easily 5-6 generations old. Bethesda isn't Valve, so it's highly unlikely the game will scale well between that many generations, meaning that all "high-end" cards in the past few years will *probably* max it out.
I'm guesstimating the minimum specs as:
CPU: Intel Core 2 Duo or AMD Athlon X2 at 2.0GHz
RAM: 1GB (2 for Vista/7)
GPU: ATI 1900XT or Nvidia 7800GT
HDD: 10 GB of free space
OS: Windows XP
DVD drive
Keyboard and mouse
Recommended:
CPU: Intel or AMD quad core at 2.4 GHz
GPU: Radeon 4850 or Geforce 8800GT
RAM: 2GB (3 for Vista/7)
Xbox 360 controller for Windows
