i just found a great deal on a 9800 gtx 512mb for less than $150 plus COD World at War (dont care much) but it says on the site that 9800 doesnt come with HDMI. how would i check if i have an hdmi plug?
You would use an HDMI cable to hook your computer up to an HDTV.
Purpose-built monitors use VGA or DVI cables.
