if you can wait a month or two - HD7850s price will come down further.
After a months I think so hd 7850 2gb versions will cost max upto 13k
2 months and one month is a long time .... Do nt really know whether prices will come down or not ... same thing happen while purchasing my rig during this feb ... dollar has came down to 50 but still these people have nt decreased the prices ... they always increase the prices for a reason but never decrease ....
