I am due for a graphics card update.. I am still rocking my gtx480 lol. My price range is between 300-400 dollars. I prefer Nvidia cards but my price point is pushing me to AMD. I see I can get a reference model Diamond R9 290 for 369$ ..getting the newer ones with better cooling pushes the price up on avg 100$ bucks and out of my limit. I see R9 280x's are going for around 300 and up (with non- ref coolers) and I was wondering should I take an R9 290 ref over a newer R9 280x? Are the problems with heat that bad?
