I am on the edge of buying a new gpu, when i noticed that the gpu is 128 bit, but it has 4gb memory space, should i really buy this? I researched for an answer and i found that having larger memory is good, but i also researched that having a very low bit bus in a large memory is senseless, should i just buy a 2gb 128bit video card?

Depends. Games start pushing 4GB VRAM amounts when you're maxing graphics settings. When you max a lower/mid-end GPU, with 128-bits of memory bus, you're going to struggle for framerates in the first place.

It depends on the price. Which GPU are you talking about?
