System Usage from Most to Least Important: Gaming, Watching Videos, Surfing Net

Preferred Website(s) for Parts: I have to get my parts locally, since I'm not sure newegg ships worldwide

Country: Singapore

Parts Preferences: I would prefer an Intel powered computer and Nvidia GPUs

Overclocking: Yes

SLI or Crossfire: Maybe

Monitor Resolution: Up till 2560x1800(e.g.: 1024x768, 1280x1024, 1440x900, 1600x1200, 1680x1050, 1920x1080, 1920x1200)

Additional Comments: I will want the computer to last me for around 4-5 years before I upgrade.

So here are the specs and the prices that i can get them at(in sgd with usd in brackets)

Case : NZXT Phantom usb 3.0 - 229
Motherboard + Processor : ASROCK Z68 Extreme7 Gen3 + i7-2600k - 889(686)

Anyway I can make this rig better or cheaper?


General Questions
- I've heard not very nice things about the longevity of selfbuilt systems, so can such systems last? If so, on average how long?

If you can wait another few weeks for the new AMD 7970 to come out it would be better. Also you don't need the 2600k better go for 2500k and just overclock, plus the PSU is too much, go for something around 800W max. If you buy the cheaper CPU and PSU, and maybe take out the Network and Sound cards (the motherboard has a good ones) you can go for a SSD which would realy increase your general perfomance.

Yep, I agree fully to what everyone said above.

And really a self built system will last just as long or longer than a pre-built computer. An Alienware/HP and this PC arnt really that different if you think about it. They still get their parts from other companies, and all those parts are put together by a bunch of people being paid too little. Sometimes the company will use cheap PSUs and then the whole computer will die earlier. And since nothing uses shitty capacitators anymore there really isnt any reason to be afraid of your computer dying earlier than normal.

Good luck and lots of fun with your new build! It looks awesome!
