How much it costs you total?
PC is better than console because you can only play original version of a game on console while on PC you can customize the whole game by downloading add-on from the web.
yeah true you can do customization and also 'real time strategy games' and 'turn based strategy games' are more fun over PC but these days not so many games are being made for PC. Where as even now 360 and PS3 will get new games at least for sometime.
About 120,000.- PKR including everything from components, to monitor, displayport adapters etc.Could probably get the parts cheaper from USA or Pakistan though.
