I need a powerful HTPC cum download rig. currently have a Q6600 with Nvidia 8800 GTS.I Don't want to compromise on video quality. want to upgrade because of lower power consumption(hopefully) and constant BSOD's currently which i am unable to fix.
Still you needn't get the Core i3 always.
You can go for this configuration instead --
Intel Pentium G630 ~3500/- OR Intel Core i3 3220 ~7000/- (this is the price in Nehru Place)
GIGABYTE-B75M-D3H ~4500/-
Corsair ValueRAM 4GB x1 ~1200/- (add another module later for dual-channel advantage)
Hope this helps, Cheerio!
