Thanks everyone for the suggestions!
based on going through another thread of similar requirements, i've suggested to my friend the following config-options
OPTION #01:
CPU- I5 3570 3rd gen
Mobo- Gigabyte GA-H77-DS3H
PSU- Seasonic 520W
GPU- ASUS GTX660-DC2TG-2GD5 (13500)
RAM- G.Skill RipjawsX DDR3 4 GB
Cabinet- NZXT Gamma/Bitfenix Merc Alpha/CM Elite 310, or any good cabinet which falls below 2500/-.
OPTION #02:
CPU- AMD FX 8350
Mobo- ASUS M5A97 R2.0
PSU- Seasonic 520W
GPU- Sapphire HD 7870 2 GB
RAM- G.Skill RipjawsX DDR3 4 GB
Cabinet- NZXT Gamma/Bitfenix Merc Alpha/CM Elite 310, or any good cabinet which falls below 2500/-.
we haven't been able to go hunting for the prices locally yet, and moreover with the LBT strike going on-off here in Mumbai, we've decided to do that on the next-to-next weekend. however, going through a few online-stores' listings in the meanwhile, the prices seem to be quite northwards of what i've read on some threads (like AMD FX 8350 being mentioned for abt 11k here on the forum, whereas online, its close to 13k or more, etc.).
he is open to pursuing the AMD set-up way too, primarily if it means lesser expenditure for him. he insisted on searching for another AMD processor which would be cheaper than FX 8350, but i explained to him that having a 7870 with a low-end proccy may result in the proccy bottlenecking your GPU, and hence go with the FX 8350 only. would like to know whether am i correct in my assumption? or, is there any other AMD proccy as well, cheaper than the 8350, which won't drag down the 7870? a rough estimate shows that even the AMD set-up is crossing the budgetary-limit, and hence we've decided to postpone the purchase of the GPU till 15th of June, to see if AMD reduces prices of their GPUs in the wake of Nvidia releasing their newer GPUs.
