If you wanna sell your old components then forums are the best place to do that. Here people understand the true value of a components and don't judge things by just brand name. It is strange that before even buying, you are thinking about resale value. Buddy, FX-8350 is powerful enough to fulfill all your need for next couple of years.
Regarding Gfx card, I strongly suggest you to go with at least HD 7870 and Sapphire HD 7870 is available within 17K. It performance is just slightly behind GTX 660 Ti which costs almost 20K.
For PSU, if you're going for HD 7870, a good 500W PSU is recommended. However, my pick is still a 600W PSU like Corsair GS600 as it will let you overclock your components safely.
The Motherboad you are talking about is based on 990X chipset which is slightly inferior to 990FX chipsset. I strongly suggest you to go with MSI 990FX-GD65 @ 9.03K or Gigabyte GA-990FXA-UD3 @ 9.5K. Both of them are available in Flipkart and Smcinternational.in. You can purchase online from there if they aren't locally available.
