What to look for in video card and computer monitor?

What to look for in video card and computer monitor other than saying it supports 1920 X 1080 P resolution or higher?



What should the contrast ratio be at? How does the response time and hertz help?|||Monitor - Desired Specs:



Resolution: 1920 X 1080 (Full HD)

Contrast Ratio: 50000:1 min (higher the better)

Response Time: 5ms minimum (lower the better)

Refresh Rate: 60 to 75 Hz (120 Hz is 3D ready)

Connectivity: VGA, DVI-D, HDMI



The Refresh Rate (Hz) defines how many times the image is refreshed per second. So for 60 Hz the image is refreshed 60 times per second. A 3D monitor requirs images to be refreshed at very high rates and thus 120 Hz is the minimum requirement out there.



Response time is the amount of time a pixel in an LCD monitor takes to go from black to white and back to black again. It is measured in milliseconds (ms). Lower numbers mean faster transitions and therefore fewer visible image artifacts.



The contrast ratio is a measure of a display system, defined as the ratio of the luminance of the brightest color (white) to that of the darkest color (black) that the system is capable of producing. A high contrast ratio is a desired aspect of any display.



In a Video Card:

Amount of RAM - 512MB / 1GB

RAM Speed - DDR2/DDR3/GDDR5

No. of Stream Processors - Unit measurement varies for NVidia and ATi

GPU Clock Speed

Connectivity - VGA. DVI-D, HDMI

Good clooing solutions (Fan with heat sink)

Interface - PCIe 2.0

Memory Bus Width|||check out www.tomshardware.com there are ratings and prices for all kinds of things like that
