Brothers,
From reading past articles on high end SLI setups, I have noted that scalability is restricted by CPU speed. For example, in some tests I have seen that 2 GTX 280 in SLI will actually lower frame rates in games (as compared to single GTX280) when there is a less powerful CPU driving the system.
Having also read the current article on Tom's that illustrates how well the GTX280 scales with the core i7, I noticed that the stock speed Q9770 (I believe it is stock at 3.2 GHZ no?) allowed much better scaling than previous tests I have seen that utilized a 2.93GHZ processor.
My question then, as I own a Q9450 overclocked to 3.2GHZ, is do you think that 2 gtx 280 would scale well with this CPU (I have 780i motherboard by the way) or do you think it would perform poorly in SLI with this CPU and 780i combo?
