NVIDIA revealed yesterday the new GeForce 280 GTX GPU. Tweaktown already got their hands on three of these new cards for some serious tri SLI testing.
Quote from the review: "It was always going to happen; the testing of two and three GTX 280 cards. We had hoped to have had it ready by launch date, and we’ve fortunately done it with an absolutely massive weekend that has involved over 250 benchmark runs across four different motherboards. Before we get into it though, we have to laugh at our power supply situation. When we started testing our Tri SLI setup with a 1000 Watt Zalman PSU, we ran into some problems. During the Canyon test on 3DMark06, the system would just shut down! - Since this would seem to resemble a power problem, it was time to pull out a HX 620 Watt and do a bit of ghetto modding to get the two power supplies working together. What we ended up doing is running one GTX 280 off the Corsair HX 620 PSU while the 1000 Watt took care of the other two cards and the rest of the system."
