Hi guys I am stuck in a big time choice. I need to select from the zotac synergy edition gtx 660 and the sapphire dual X r9 270 (non X). The gtx 660 is 199$ and comes with free watch dogs. On the other hand the radeon r9 270 is 180$ and comes with two old games which I have already played. I like the radeon card more but at the same time I want to play watchdogs.(watchdogs for 25$ is awesome considering there is not much difference bwteen the two gpu's) Which card is better? These both cards are almost the same performance wise but how much difference will it make in 1080p gaming. Plus most of the games I want to play on my pc are NVidia sponsored.
