I'm thinking of buying a new video card - GeForce GTX 550 Ti, off. The site says that it has a slot - PCIe 2.0 x16. Now I have a GeForce GT 340, and the slot is PCIe 2.0. The computer was bought assembled (Acer), and I did not find information about the motherboard. The question is, will a new video card fit?

This is the same thing, in the same way as the standard, i.e. you can't talk about backwards compatibility. Those. and both are PCIe 2.0.
x16 is the number of data lines. x1 - short connectors are used for low-speed peripherals, various simple network cards, audio, usb and other similar controllers.
Long x8, x16 are mainly used for video cards. If there is only one connector, it is probably x16, the second and then x8 happens, this can be found in the documentation for the motherboard, usually.
