1. ACX vs ICX. Some articles said ICX was more effective at cooling, while others said they were the same. Any personal experience with the 2 cooling methods? Which would you buy if price was the same? 2. Some ACX cooled cards have had problems, and EVGA gave away thermal pads or something else to fix. Is it wise to avoid used ACX cards? In other words, no way to tell if an ebay seller applied any fixes. This would be for a 10 series card. 3. Conventional wisdom used to be to not pay extra for overclocked cards. My understanding is that EVGA has stock clocked, superclocked, and FTW with increased out of the box clock speeds for each of the 3 categories. Is it still the best value to get the stock clocked gpu and manually overclock them? I am assuming the result would be close to the more expensive cards, subject to luck of the draw ("the silicon lottery").
