Hello!

This is my situation:

I want to buy iiyama ProLite G2773HS 120Hz monitor, Asus P8H77-V LE motherboard and Intel Core i5 3570K processor.

This is my reasoning:

I want the 120Hz monitor only for quakelive. Quakelive will work perfectly fine with the integrated graphics of that processor so I don't need a discrete gpu.

This is my question:

Will it work at 120Hz when I connect the monitor to the motherboard's DVI-D?

I am asking because in the motherboard's specifications it says the following:

Integrated Graphics Processor
Multi-VGA output support : HDMI/DVI/RGB ports
- Supports HDMI with max. resolution 1920 x 1200 @ 60 Hz
- Supports DVI with max. resolution 1920 x 1200 @ 60 Hz
- Supports RGB with max. resolution 2048 x 1536 @ 75 Hz
Maximum shared memory of 1696 MB
Supports Intel® HD Graphics, InTru™ 3D, Quick Sync Video, Clear Video HD Technology, Insider™

But according to this calculator:
http://www.emsai.net/projects/widescreen/bandwidth/

1920x1080 @120Hz uses "Bandwidth: 8.86 Gbit (w/overhead) or 248.83 MHz."
and "DVI-D Dual Link = 9.9 Gbit (330 MHz)"

Please explain, I'm noob.

ps I know it's weird to buy 120Hz monitor and no GPU but I can alway get one later on.

The res frequency it what you will run at. The monitor will support upto 120 Hz. Personally I look to the millisecond rate of the monitor. 2ms vs like 5ms. Lower the better for smooth FPS. As for the Hz. The human eye/brain can't detect beyond 50+Hz anyway.

From the specs you list it sounds like the DVI-D port on the IGP is not dual link, so I don't think it will work. DVI-D plugs come in both single link and dual link, dual link has more pins and more bandwidth.
