Will upgrading my late-2009 iMac Radeon card help AE performance?

I saw this iFixit link (see below) about upgrading iMac late-2009 Radeon graphics card, which will give a performance boost for gaming. Will it, however, give a performance boost for Adobe After Effects and Premiere Pro CC 2015? If yes, is it significant enough to make the upgrade?
