The MSI 780 Ti has been $600 on newegg every other week for last 6 weeks.....start looking around Thursday
Finally, consider the MSI GD-65...it's a virtual feature for feature match up and down with the Hero, is better reviewed and is $40 cheaper. I love Asus but until the BIOS Clock Freeze thing is fixed, I put a hold on any more builds.
If ya do a web search of RoG forums, there's about a dozen threads on this issue. Asus announced a fix back in August but was only temporary, same with removing / replacing battery ... only temporary. The kast fix was announced in June 11 but teh promised BIOS update that is suppossed to fix it was not available as of yesterday.
If ya can wait, then by all means wait for the fix.... not that I don't trust them at their word but we have seen fixes announced before that just didn't "take". The fact that we still can't get the fix 2 weeks after announcement that it was available has me a little nervous.
