Exactly.. Flipkart is 1GB version and MDcomputers is non-OC version.
I really don't know how much difference it is going to make (1GB vs 2GB and OC vs Stock) but I dont want to settle with less, if I can afford a few hundred bucks more![]()
2GB against 1GB is going to make difference in some of very intensive games like BF3 @ ultra settings and in intensive 3D work. It would be future proof to opt for 2GB model.
Regarding stock vs OC'ed, if you don't want to take risk of OCing, then go for factory OC'ed, or if you don't care for the extra 10-15% performance gain at all, then get stock.
