Just curious if you'll forego updating your BIOS so you don't lose the TSX instructions, despite the errata?
Hopefully you can upgrade to a Broadwell or later once Intel starts shipping fixed silicon. Haswells will be updated to the new microcode once a replacement is available. (At least, that's our plan.)
Since I'm having no problems, I'll likely forego updating the BIOS. However, that might not mean much since I think Microsoft distributes Intel microcode updates as part of OS updates. But usually you can remove the specific kb patch if needed.
But yes, I'll be looking forward to the replacement Broadwell. My previous workstation was a Core 2 DUO E8400 which I just replaced with the 4790K.
