Does someone know what is the equivalent of the Radeon R7 240 GDDR3 from the older generations in terms of performance? Does it perform like the HD 6670 GDDR3 or worse? I know this card is really slow, but it's really cheap in my country (even cheaper than in the US). I know I can get something more powerful for a little bit more, but I need to save for a pretty long time for such card. Also, if I get something more powerful I will experience a bottleneck by my CPU (Intel E5300), and my gaming experience will be laggish. Thanks.
