If the gpu-z screen has the blue question mark on the side, that means you are Ok, because when you don't run the game for the hd7770, it will run in lower speed for energy saving mode, you just click the "?" to run GPU load test to verify PCI-Express lane configuration.

Yes it has blue question mark..means OK? But when I starts render test it reached to 2.0 standard
So it will go 3.0 based on high requirement.??

Maybe your Processor supports only PCI Express Revision 2.0

Like Josmar said, I guess you have either i3 3225 or i3 3220, because the cpu only support the pcie2.0X16, http://ark.intel.com/products/65692/Intel-Core-i3-3225-Processor-3M-Cache-3_30-GHz so that it shows the 2.0 version. But you will not see the big different in performances between pcie2.0 and pcie3.0. Here is the review for high end PC. http://www.pugetsystems.com/labs/articles/Impact-of-PCI-E-Speed-on-Gaming-Performance-518/

yes i have i3 3220... and yesterday i had talk with Gigabyte representative.. as they said...u will get full performance from ur card if ur card is minimum 2.0 standard..when application require high rate data, it will reach to 3.0.. and btw ..the link u mentioned for for performance stat, its great..theirs no much difference between them....and here is the link of supported cpu for my mbr... Gigabyte CPU support list .. it says if u have 22nm cpu then u will get 3.0 support for ur card..and i3 3220 is 22nm processor with ivery bridg....
