Hi guys, Just under a year ago I bought myself a GTX 570 2.5GB. Have had a lot of fun with it over the last year or so and it works like a charm. I haven't yet overclocked it as I haven't had the need. I game at 1920x1080 at the highest settings always. Now I have been keeping an eye on the market for a second 2.5Gb card to setup SLI. My system is in a great position to get an overclock to match current gen rigs with ease. I don't yet need to do so but I am thinking about it for early next year. However, I am also acutely aware the GPU market is moving on quickly and getting hold of a new GTX 570 from the market without paying a premium for low stock may soon become difficult. Hence, my first question is whether we have any info about Nvidia stopping production of GTX570 cards in the near future? Should I think about buying my second card soon or am I ok to wait a few months, maybe until the new year? Secondly, if I was to get a second, I am correct in the thinking I can add any brand card to my current POV GTX 570, and when in SLI the speed will be limited to the slowest card....I am happy to overclock one or the other to match speeds. At present EVGA 2.5GB cards are a LOT cheaper than POV, though they are faster and have a far better passive cooler on the POV. Thanks all in advance!
