Main reasons to opt for this gigabit setup:
1. More than 10MB/s speed when downloading/uploading from/to torrent bd.\
2. Massive reduction in ping.
3. Lan matches are fluid as playing in split-screen.
4. No more worries about thunderstoms

. As current does not pass on lights.
Things you need to get the whole setup done:
1. Talk with your ISP to get a direct line from the IIG. Your ISP will just be a pass-through then. Charges a premium ofcourse.
2. A minimum of 4-core fiber optic cable. 20tk per meter.
4. A Gigabit ONU. 4000tk each.
5. A minimum of Cat6 patch cord. Cat7 is preferred.
6. A good Surge Protector for current lines. Belkin preferred.
7. A Gigabit Lan card. Intel preferred for its less cpu overhead and higher bandwidth.
8. An ssd. Cause it look really odd if you suffer from low-write speed due to your mechanical HDD.
Whole setup costs around ~20,000/= only.
