I registered on this forum just to publish my solution.
Thanks for recommending "driver genius professional edition" - it helped to find correct version of drivers without paying for this software.
So I had almost red DPC while Skype and other Internet activity and it made it hard to talk and listen to music on modern Core i5 with SDD laptop! With the help of DPC Latency checker (btw it worth checking LatencyMon to get additional details) I found that it was WiFi adapter - Atheros AR9002WB-1NG and Ethernet adapter - Atheros AR8151 PCI-E.
Drivers which helped to eliminate DPC issue:
ATHEROS AR5xxx/9xxxx Wireless Lan drivers WHQL
ATHEROS AR813x/AR815x/AR816x Ethernet Controller, drivers

Thank you! And make sure that DPC issue will never frustrate you again! :)
