Additional Comment : Its my 1st time to actually build a real gaming rig as well as my workstation (for minor typing works).. Now I need some advice on my build, my target is a descent gaming system..

Question : with similar prince range as on my mobo the ASrock Z77 Extreme 6 is there any other options? as also Iam looking for a stable mobo for overclocking. Preferable Asus or Gigabyte beside ASrock ...dont get me wrong is just that the warranty for other brands like (MSI, EVGA, ECS etc) will be time consuming as the other brands are consider as a small player in my country. Here we can purchase those high end flagship mobo's just that the warranty would be a problem "if" u encounter problem. For the CPU for light photo editing does i5 will do an outstanding performance?

Your advice is highly appreciated, this is my 1st post I've been following the forum for the past 4 month before deciding to build my rig.
