1. It actuallt depends on the RAM you are getting. If you are getting Corsair Vengeance then you can't install D14 very simple. Also D14 is heavy cooler so I think your Mobo should also be very sturdy. I am not sure about this, let others comment.
If you get U12P then you are alright with everything. If you can't find it then you are between 212 EVO and A70. I would say that if you have money then you can buy A70 also but if you wanna save money then go with 212 EVO.
As for GPU Asus 7970 Matrix performs the best but its also higher on the price side. Sapphire 7970 would give you best VFM IMO.
i wont be going for vengeance modules but will get this instead G.Skill RipjawsX DDR3 8 GB (2 x 4 GB) PC RAM (F3-12800CL9D-8GBXL) - G.Skill: Flipkart.com
still looking for noctura (will probably buy the cpu cooler last depending on availability)
still to decide on gpu...
i was thinking of ordering the psu CORSAIR Enthusiast Series TX750 V2 750W ATX12V v2.31/ EPS12V v2.92 80 PLUS BRONZE Certified Active PFC High Performance Power Supply and ram from flipkart tomorrow..
any last minute recommendations...
