I'm not generally familiar with prices in India, but looking at the site you listed, I believe it would be difficult to build a computer that can play the top games for the next 5 years at that budget.
In your build, it can certainly play games today.. (well, most games today), but the core i3 will hold it back over time as games become more highly threaded.
Do you anticipate upgrading the CPU over that time (and the video card as well)? Or are you looking for something that can work as is for that period...and can you increase your budget if that's the case?
Well I am looking for something that can work as is for that period. I don't think the games industry is going to invest in graphics any more as more developers will be focused on consoles . And as far as the leaked specs of next-gen consoles go they aren't too good. Those games will work on this config just fine I guess. F2P and cloud computing seems to be PC gaming's future.
And more hardware and software methods are evolving like FXAA that is way good in performance compared to supersampling.
I need a confirmation on the compatibility check on this config. This config does have USB 3, SATA 6Gbps, and the mobo is PCIe 3.0 ready(well i actually do not care about that)
