I am going to build a new PC pretty soon, but I am holding off on getting a new GPU until I have a little extra cash to really get something good. My question is whether or not a Sandy-Bridge/Ivy-bridge integrated graphics solution will run The Witcher at a playable framerate. I want to do another full play-through of this game before I upgrade to a "Witcher 2 ready GPU" so I can import my saves. Can anyone shed any light on this for me? I can't find benchmarks for this game/graphics solution anywhere.

Hi, I'm running the game on intel hd 3000 which is around the same performance. It's smooth though you will need to use 'dontforceminreq' thingy to start the game as none intel graphics where able to run the game at it's release and are not recognized by the game. Meaning you will get error 'system req not met' at first. The new generation (intel hd 3000 including) is able to run the game fine. don't expect miracles though...
This will also block the textures settings in game to lowest value. I'm able to play the game with high/medium on everything, but textures are fixed to lowest and it's not an entertaining experience I can tell.
Trying to get some help on that one in another threat.

I think you'll be alright if you're careful with the settings. Towards the end of the game there is a thankfully brief but nevertheless highly graphics-intensive part that you might struggle with. My framerate drops noticably, and I'm running a GTX 560 Ti (at maximum settings). I did complete the game with my old laptop though, and it had a relatively weak GeForce 8400M GS. Said part slowed the game to a crawl even on shit-end settings all around, and I wouldn't go so far as to call it playable, but once you kill the baddies the choppiness doesn't matter gameplay-wise.
