I now know that my pci-e slot version is 1.1
People say that 7750 hd will work slower :-(
If so, how much slower will it exactly work?
One guy even said - JUST LIKE 6570 ON PCI-E 2.0 DUDE.
Is it so?

I don't think the performance will drop much. BTW, what's your CPU and mobo? The HD 7750 is equivalent with HD 5770 but it needs other parts' cooperation

Your performance bottleneck probably won't be the gpu memory speed limited by pci-e 1.1. It will be other factors related to other components on that mobo with pci-e 1.1. So don't worry about it.

And 7750 in pci-e 1.1 is NOT going to feel like 6570 in ANY slot. GPU performance doesn't slow with the slot, only the gpu memory bandwidth, and only certain things that requires lots of data transfer are effected by it (high-res gameplay, etc). Typically, the difference is 2~10%, related to pci-e slots.
