The error is Immibis Microblocks (says it right at the top); your video card is fine. Make sure the config file is being placed in your config folder (which depends on where you downloaded FTB/FrogTEK). You also need to make sure you are not changing the file extension or anything else or the mod will regen the config and you will still crash.
Absolute worst case, you can open the config file in your config folder and change this line…
make absolutely sure the file is “immibis-microblocks.cfg”, not “immibis-microblocks.cfg.txt” or anything else.
