EDITOR’S UPDATE BY IMOG: I received this message from Allan Stirling, issuing a warning about the dangers of using your oven for this. I haven’t seen much discussion of these sorts of concerns, and I’m not sure how valid they are. That said, the reader should take these into consideration prior to deciding to attempt the oven trick. Contact me at matt@overclockers.com if you have any feedback, confirming or contradicting Allan’s concerns :

No-one should attempt this in a household oven, for various reasons:
1. Both lead and tin are volatile when heated. Specifically, this means that lead oxide and other dangerous chemicals are emitted when lead is heated.
See:

2. The fluxes used in production of modern electronics are designed to remove oxides very, very efficiently. They are NOT designed to be biocompatible. Small amounts of residue may still be on the board.
3. Boards may contain parts which will melt at the reflow temperature. These components are generally through-hole and added as a separate step.
So, basically, once you have completed this operation and (possibly) fixed your video card, BUY A NEW OVEN.
The other option is to buy a cheap toaster oven and use it only for reflowing – however, that’s cost prohibitive.
