Will it be a strong Solder smell? When I took it out the board smelled just like super hot hardware, so I'm guessing it wasn't enough then lol.
Sounds tasty, how about some white chip macadamian nut?
And in all seriousness, don't bake something while the oven has GPU in it. Bad gasses are released from the solder that would get on the food potentially making you ill. I'd recommend putting the oven into cleaning mode after you're done with the GPU before you put any food in it just to be safe.
