Best desktop prices in Islamabad

I wanted to buy a good branded desktop from Blue Area or somewhere but I have no idea what prices they have and I can't visit due to a few reasons. So anyone have any idea how much a core 2 duo or core i3 costs (whole desktop) ? At the cheapest?

I heard that galaxy is very bad, so I'd like to stay away from them.
