Hi all! It's my first post here even though I read T|I for some time now. Following this thread for nearly 6 months, I was thinking about replacing my GPU by a 970m. Now it's mandatory as it seems my brave 7970m just passed away. My question is simple: owning a XMG P502 (P150EM), is it directly possible to upgrade from a 7970m to a 970m without buying an upgrade kit, just the graphic card? I've seen posts about upgrading from nVidia to nVidia, but nothing really convincing about AMD to nVidia. Particularly I wonder if the X bracket is compatible (same form factor, but what about components placements?). I'm not very familiar with laptops upgrades/modding, it's a bit different than its PC counterpart! Thanks all, and thanks Prema for making this upgrade possible!
