MSI GD45 Gaming cost almost 17k inr. I can go with a mobo of 10k inr maximum right now. If there is no sli mobo near this price I have to go with a non sli mobo. Also I am not sure if I will be overclocking the CPU, so if I buy i5-5670/i5-4570 instead of i5-4670k will this bottleneck with gtx 780 and gtx 780 sli. Cutting down in CPU cost will allow me to increase the budget for the mobo by 2-3k inr. I will not be doing any video rendering or stuff. My maximum budget for CPU and mobo combining is 25k inr.
17k inr... that price may be close to gigabyte z87x-ud3h or asus z87-plus.. or pro.
10k inr.. is too low for z87 motherboard with dual pcie x16 slot capable of running at x8+x8 mode. that price gets you usually b85 chipset motherboards, which don't have sli support. i see only 2 core i5 cpus on flipkart - 4430 and 4670k. you'd need something like a 4570 - but i think the price of 4570 may be too close to 4670k (in that case getting 4670k would be better even if you don't o.c.). non-k i5 won't bottleneck a single card much, if at all. but sli will see improvement from higher clockrate/overclocking.
25k inr is just too low for a good intel multi-gpu capable config. for that budget, have you thought about amd fx8350 with 990fx chipset motherboards? how much do those cost over there? according to flipkart, you can get an sli capable amd motherboard rather cheap, like gigabyte 990 fxa-ud3 or ud5. you'd have to o.c. to fx8350 to get more out of the gfx card(s), though.
