My desktop machine is about 4 years old. It has an i7-2600 CPU @ 3.4GHz, with integrated Intel HD-2000 graphics. Right now I'm using a 1920 x 1080 IPS monitor, but would like to upgrade to something larger. Problem is, the only video outputs are VGA and single link DVI. Also, I gather that the HD-2000 graphics is limited to 2560 x 1440, and that would in any case require dual link DVI. There is enough space inside the case for an external graphics card. Am I right in thinking that this would bypass the integrated graphics completely, so I could upgrade to any size monitor? Or is there some other limitation? Obviously one option is a new computer, but I'm reluctant to do that since I'm perfectly happy with the present setup ... apart from the display.
