The entire guide is updated bi-weekly or shortly following major product launches. I uploaded the last update on August 19 and the next update will go live this week, but I don't anticipate any major changes. Just pricing updates etc.
I don't know enough about either game to offer anything conclusive, but considering WoW's age, I'd like to believe an HD 6770 could run it at max. I've run the game on a PCI Radeon 9200se (an entry-level card from the early 2000s). Generally speaking, MMOs scale very well and I'd expect the HD 6770 to handle SWTOR.
