I currently have a reference cooled r9 290, i want opinions on whether i should sell it and buy the 920 with a gigabyte wind force cooler or similar on it, or whether i should just get a g10 bracket and the X61 to keep it cooler. What will be the difference in performance and temps between each, i need it to keep a lot cooler as my room tends to get very hot in summer(i'm in Australia). So opinions on what option to go for would be appreciated and why. Thanks
