You have a socket 1155, it works with PCI-E 3.0. In General, PCI-E 1, 2, 3 - they are all compatible, and everything will work, the only difference is speed GB/s (well, food - cards without additional power).
Lying at H61 PCI Express 2.0, the processor supports PCI Express Revision 3.0.
Put and do not worry. The mother of the modern socket 1155 actual difference between 2.0 and 3.0 is practically not - insignificant percentage.
Meanwhile you have written in the second screenshot Bus Interface - PCI-E 2.0x16.
Acer Aspire MC605 - as indicated by a computer 9судя on Google), not the motherboard.

Yes, all pull, PERC quietly reveal a card.

pci-e there is no difference.. from like 2004... they all compatible

What about the memory? Because assovskii vidyuhi type my GDDR5 and GDDR3.

GDDR5 the modern version, although it appeared GDDR5X. This concrete elements of a graphics card, which improves its performance.
You said don't worry, bet you don't. Want to know more - Google, everything is easily found and known, really simple questions.

Sorry for another dumb question, but is all modern motherboards have the same connector for the video card?

Yes. The graphics card requires a PCI-Express x16, well, originally you were interested in a version of, well, she, in turn, in this case 2.0.
Come to the store and look at the motherboard, and you'll see that this connector is on all of them, and sometimes, even, not one, under SLI, for example, there are different variations of it, in addition, X1, X4, X8.
And here's a link to the resource, and the picture is there:

In short Yes, if the description is PCI-Express x16 slot, you can not even look - he is. It is a connector for the video card (and anything else you can stick). The graphics adapter is anywhere, in any system unit, although now it is accepted to do the integrated video core, well, it's about CPU.
Similarly, it is enough to visually remember what it looks like, and description is not necessary.
