Maximum PC: Just how good is Intel's integrated graphics on Haswell (codenamed GT3), the successor to Ivy Bridge? In due time, we'll answer that question with some numbers and a hands-on evaluation, but in the meantime, we've put together a little challenge for our readers. Maximum PC Deputy Editor Gordon Mah Ung captured on video a pair of systems running DiRT Showdown. One was equipped with a Haswell part running integrated GT3 graphics, and the other was rocking an Intel Core i7 Ivy Bridge processor paired with a discrete Nvidia GeForce GT 650M GPU. Let's see if you can tell the difference. (CES 2013, Intel, NVIDIA, PC hardware)
