My board is Gigabyte GA-EX58-UD5 Intel X58/ICH10R Qpı 6.4GT/s DDR3 2100+MHz Core i7 LGA1366 Anakart PCI 2.0
My Cpu is Intel Core i7 920 2.66GHz 8MB Cache 45nm Lga 1366
..So what i want to do is upgrading my gtx 750ti to msi gtx 1060 and 8 gb ddr3 ram... What do you think? Do i lose game fps or performans for single card due to its being pci 2 instead of 3? I dont want to change my mainboard and cpu because no game make them reach full power...
What do you think?

Your processor will bottleneck the GTX 1060 a little but i wouldnt worry to much about it. You will see your cpu usage running at max now with the new card.

Thanks for your input! Can u give me a percent value for example? %10? Will it decrease fps to a good extent or a few? Or stuttering etc?

The difference in graphics performance between pcie2 and three is very small. and negligible with low end graphics cards.
With top end cards, perhaps 3%

Here are some tests to see what you can expect:
------------------------------------------------------------
To help clarify your CPU/GPU options, run these two tests:

a) Run YOUR games, but lower your resolution and eye candy.
If your FPS increases, it indicates that your cpu is strong enough to drive a better graphics configuration.
If your FPS stays the same, you are likely more cpu limited.

b) Limit your cpu, either by reducing the OC, or, in windows power management, limit the maximum cpu% to something like 70%.
Go to control panel/power options/change plan settings/change advanced power settings/processor power management/maximum processor state/
This will simulate what a lack of cpu power will do.
Conversely what a 30% improvement in core speed might do.

You should also experiment with removing one core. You can do this in the windows msconfig boot advanced options option.
You will need to reboot for the change to take effect. Set the number of processors to less than you have.
This will tell you how sensitive your games are to the benefits of many cores.

If your FPS drops significantly, it is an indicator that your cpu is the limiting factor, and a cpu upgrade is in order.

It is possible that both tests are positive, indicating that you have a well balanced system,
and both cpu and gpu need to be upgraded to get better gaming FPS.
