AMD Radeon R7770 TDR BSOD problem, please help

You guys have probably gotten this a lot in the past (having google searched and reaching this site many times) but I recently got an R7770 to replace my old GT440 and I just can't seem to get rid of this problem with the display driver stopping and restarting (atikmdag.sys) but still giving me a BSOD. It seems to be on a case by case basis, to list off a few games I play and specify if I get a BSOD during gameplay:

1) Phantasy Star Online 2 (only ever got it once and it stopped when I set CCC to force V-Sync systemwide)
2) TERA (as of this topic, this has only happened twice, barring the game's poor optimization for anything not in Korea's hardware range)
3) The Elder Scrolls V: Skyrim (Just about every session after some time)
4) F.E.A.R (ditto)
5) Dead Space 1 (BSOD on startup but even though CCC has V-Sync forced on my 60Hz monitor, Bandicam's FPS counter reads Dead Space going up as high as 900+ FPS before the whole thing implodes, this in particular concerns me) Dead Space 2 (nothing, perfect), Dead Space 3 (same, perfect)
6) Darksiders II (a BSOD occurred frequently at one particular location that CCC's V-Sync rectified, so this as far as I know, runs perfectly as of this writing)
7) Metal Gear Rising: Revengeance (perfectly fine)
8) Injustice: Gods Among Us and Mortal Kombat Komplete Edition (both run perfect, with SweetFX enabled for both)

When idle, the computer is just fine, it boots up fine, I can watch videos just fine, I can emulate as good as the emulator can get (PCSX2 in particular runs perfectly fine). Running MSi Kombustor shows the card at 40 C at rest and ~60 C when at 99% load for the past 30 minutes (somewhat steady 60fps, Direct3D 9 mode, Horus). I didn't OC anything at all from general paranoia. At most I use 4x MSAA on TERA with maybe 8x or 16x AF on the games that didn't trigger this BSOD. My system specs are:

AMD Radeon R7770 (MSi 1GB GDDR5 128-bit)
AMD FX 4100 Quad Core 3.6GHz
MSi 970A-G46
8GB RAM
Windows 7 Ultimate x64
Rosewill RG630-S12 630W PSU, 50A on the 12V rail (the R7770 says it needs 450W minimum, I went ahead and got it some extra juice from a brand I like)

I've updated my R7770's drivers several times, cleaning it completely via Safe Mode + Driver Sweeper, I updated my motherboard's BIOS yesterday, which aside from making the PC boot incredibly fast, didn't stop the BSODs. If anyone who can read through dumps wants, I have a dump file on hand and if you tell me which upload site this forum prefers, I'll upload it there and post. One thing peculiar about this is the first BSOD (PSO2) and various other ones concerning this driver happened around areas of the game with a lot of water. I'm not sure if that's relevant at all but whatever. I hope to get a response and hopefully some good news.

Thank you.

Tried the beta earlier, didn't last a second in 3dmark, it didn't even give a BSOD, it just made the computer hang completely. As I said in my first post, I didn't overclock a thing due to my own paranoia about this stuff lol. Would rolling back a driver or two help (or searching for a downloadable copy of the driver that came with the graphics card)? I find it peculiar how it can act so strangely game-by-game when something like Tera, which renders an entire world and other players, can run without a hitch yet F.E.A.R, an fps made in 2005 triggers this thing.
