I call this complete bullshit. I just saw a benchmark comparison between the GT 740 (2gb ddr5) and the r7 250 ... and it killed that geforce card .... and now a ddr3 gt640 shall be able to pass scores beyond the r7 250? just look at the clocks and type of memory... the gt640 will be destroyed. I am not a fanboy, i have cards of both brands. this is just another proof that this site sucks...
lawls....... R7-250 (score of 5.7) vs. GTX-640 (score of 5.6)... Same performance and GTX wins??? And is $281 HIGHER than the R7 250?? LMAO rigged!
