So I was planning to buy an MSI GTX 580 Lightning. It's so nice. Gives me the horn. But it doesn't seem to fit the Silverstone Fortress FT02 (by 1 millimetre apparently). So I am looking for a new GTX 580. I am not bothered about factory overclocks, one way or the other, but I do need it to be quiet and durable as I will not be able to upgrade it for three years. I thank you all once again for your patience with my ongoing questions. I know they are annoying. When I have built my new machine and used it to take over the world you will be rewarded. Oh yes.
