Will it fit?

so i have nvidia geforce gt220, like the worst gpu ever, im planing to buy gt 640, like 640 is 5,7 inches and 220 is 6,6 inches.
Ive never done anything in my computer so dont really know will it fit? like can you install 5,7 into 6,6 place/hole? thanks!

If you're getting a shorter board it'll fit fine. Just make sure your case has enough available expansion slots.

Shorter mst likely

replacing a shit gpu with another shit gpu
