Graphics Card Output

[quietriot]

Does anyone have any idea about how to measure graphics card output?
The card is a Radeon Dual-X R9270X.
Motherboard is a Gigabyte 990FXA-UD5.
CPU is AMD FX8350
RAM is 16gigs 1600MHx Adata
Connecting to a Sony KDF-50E2000 TV
Sony says 340MHz through the HDMI cable will be enough for a 1080 pixel picture and carry the audio as well.
But how to determine if the output will be sufficient?
I haven't been able to find anything at all about how to measure graphics card output.
Any suggestions?
Please help!!

There are various benchmarks that can be used to gauge the performance of a graphics card, though I don't think you need worry about that. The R9 270X will have no problem outputting 1920x1080. One of the selling points of the R9 range is their 4K capabilities.

I wouldn't worry about the graphics card. Be careful what HDMI cable you use, there are different standards and some have very different speeds and/or will not output audio.

Also the length of the cable could be a factor if it's over 50 feet. DO NOT get pressured into buying the most expensive cable. Just the right standard at the best price.

Two benchmarks I have used...

3d mark is probably better, but a large file to download, you run the program and it will test and rate your video card, and show you results from other users with similar hardware, and where you stand, compared to office machines to high end gaming rigs.

They are free, but they will try to get you to buy stuff.

Ok a graphics card has what's called the base clock, which is the frequency it uses in normal use
Then you have boost clock which is its overclocked frequency
Then there is Memory. The more memory the better Fps you get with higher resolutions
Then there is VRAM which is like computer ram but its for rendering
then there is the chip, the better the chip the better the card eg the GTX titan uses the GK110
then there is what's called CUDA cores, the more cores the better a card
then there is memory speed - that's self explanatory
then there is memory bandwidth - that's how much memory can get processed at a time
then there is its power connectors - so the pin adapters that go into the motherboard
then you have TDP - which is how much power it uses
then there is output - which is what plugs it supports eg. DVI, HDMI, DP
That's it!
