Are you still having the crashing problem? If so, you could always try running config again and setting the resolution down one more notch to see what happens. It isn't like you can't put it back easily enough. Or maybe someone else has a better idea.
But I distinctly remember other people with high-res crashing issues. Personally, I've got a smaller monitor, so I only run on 800x600.
Seriously, though, I've got every mod you do except for Tactics, and then some, on my system, and it runs just fine, although I'm using G3 Fix and G3 Tweaks.
This is what my install looks like--seriously modded:
SoA, ToB, patch, G3Fix, Ascension-WeiDU, Turnabout, Xan, Banterpack, NPC Flirtpack, UB (but *not* P'Nai and Restored Minor Dialogs, because they conflict with other mods), Questpack, Zyraen's Miscellaney (select components), Oversight (select components), NPC Kitpack, Under-rep Items, IU, Victor's assorted stuff (not the official name, but I can't remember), AoE, Tweaks (select components, but most of them--they can each be installed individually, which I like), Moinesse's Avatars, DBG, G3 Anniversary, Improved Anvil
That is the mod installation order, copied from my WeiDU log. I've spent a lot of time reading the readmes, so I've been as careful as I could possibly be about installation order and not installing technically incompatible components. So far, it's working very well, no CTDs anywhere that couldn't be explained by my dying CD drive skipping (and making a horrible racket).
