Just a little sample.
As a collector and usually wanting an upgrade over what I am using at any one time I do a lot of research before I make my next purchase. My current gtx 460 was the exception as I got it early on. A few months it went like any other except I found problems early on and made sure they wouldn't brick my card later on. There is usually enough cooling for the core on most gtx 460 out there however the vast majority were made with low quality parts to satisfy a short term demand and prop up falling sales. Without cooling for the power vrm and vram most do have a shorter life than cards that do have higher grade of quality or use much less power. Basically the gtx 460 is the performance of a gtx 280 with the avg power consumption of a gt200 series in a much smaller space without any cooler either than some limited air flow from the fan. Nvidia learned it's lesson and included a mid plate on the gtx 560ti.
In the round up article there is plenty there to begin off with while the reviews on the newegg link is more directed towards the op to avoid that card. Sure they run silent but they don't last. Most get about 3 months or so if they help up that is all unless only for casual use.
Gigabyte gtx 460, I have wrote two reviews under the name Debase on newegg,. I am not the only one that has had some limited problems with the fans but they are very cheaply made and fragile. The bearings often need to be cleaned and lubed to not make grinding noises to I removed that and used a vantec bay fan, temps dropped lol. The power vrm even with the stock cooler that is reference to this card still gets hot under load so I have done a back plate mode there and not have had any problems there. Vram gets rather toasty but not to ware it is as immediate as the power vrm.
Other brands are not much better and can be much worse such as Palit while MSI and Asus are some of the best choices regardless of cost.
