Yeah, the 680's are good middle of the road cards now. More than enough for any sub DX 11 game. Trouble is with these newer DX11 games at higher resolutions, just not enough power to push much above 1080P. So, when that new monitor comes in I am going to want to run even the DX11 games at 3480 X 2400 with as much eye candy as I can handle.
I'm actually just finished reading the article about the EVGA 750 ti acx FTW edition... Boost clock reaches 1403mhz and it had 95 percent of the performance that the R9 270X... What I don't like is the 128bit bus for them memory but the 2Mb L2 cache is supposed to make up for that... For my dad's build I am going for that card over the 760 because he doesn't need the extra performance as he just plays the Dawn of War series from the mid 2000's... Here is an amazing review of the best 750 ti on the block!
