i just bought a dell widescreen 17inch vga monitor brand new off ebay. i also intend to buy an r9 380 4gb graphics card. the card has dvi,hdmi,and display port.

will i notice a huge difference between hdmi and using a dvi to vga adapter? im not too picky, but will it somehow limit my graphics card to bad quality? i know hdmi also carrys the audio , but i have good speakers with a basebox hooked up, so i shouldnt really have to worry about audio

On screens up to about 1080p resolution, I've honestly not noticed much quality difference between VGA and digital (DVI, HDMI, DP) connections when set up properly.  There is some maybe, but it's subtle.  Theoretically it depends on cable length and quality too.

 

In analogue VGA connections to LCD's, the monitor has to be synchronised with the video card output.  Symptoms of this being out are blurry or shimmering text and cross-hatch patterns.  Pressing the "auto" button on the monitor should sync it correctly (in most cases).  This step is unneeded on digital connections - it's always perfectly synchronised.  Display Port is advantageous for very high resolution screens.  Overall I'd recommend using a digital connection if possible, but VGA should be OK.

Thank you, that was actually pretty helpful and made sense. Ill just stick with the vga/dvi for now then. Maybe some other time im the future ill go to the full hdmi setup. But im happy to know i should be just fine otherwise. And its good to know the tip to press the auto fix button on the monitor.
