I have been looking at various 200-240ish dollar graphics cards, mainly the 660 and 7870. I watched a newegg vid on the 660, and he guy made a point of the shrouds on the gpus. If I am right, an enclosed shroud will have higher gpu temps, but will keep the rest of the system more cool, but if I get something like a twin frozr, it is not enclosed. That should keep the gpu cooler, but the rest of my system will have to deal with the warm air being ejected into the case. I want to know if I get a shroud gpu or a more open style gpu. I do plan on overclocking a bit on my gpu and cpu (i5-3570k), and either sli or crossfir in the future to keep up with games. Any input would be great.
