hmmm....well my suggestions are that u should hv consulted first before buying the new rig.
dnt feel bad coz i went through a crysis dis bad too once. the thing is after a year or two, the gaming world wll out-run ur current pc spec. again! den wat will u do?? thatz the real question....!
neway ur current spec is good enough to run all the games at present. The only things missin are a good Graphics Card, Storage Module and A Power supply Unit.
Listen carefully then you wont hv to spend much....
1. Graphics Card - XFX Radeon HD5670 [1GB DDR 5]
-yes the very same Graphics your friends suggested. this is by far the best G.Card in the indian markets now...its cheap,its dd5 technology, its 1GB, and doesnt use an external power source! (around Rs.5600)
2. HArd Disk - WesternDigital 1TB sata-2(around Rs.2700-tax free)
3. SMPS- get the Corsair TX650W. it might be a bit pricey but its a wise choice because in future you can avail its features. it hs al kids of outputs,supports SLI and Crossfire for graphics.multiple ports for hdd's.( its around Rs.6400)
and any querries u can contact me.
happy gaming...
