I have run a single HD4890 gpu for the last two years, along with a phenom x4 965 and 16GB DDR3. The only game I've ever had to tone down on detail to get decent frame rates is Crysis and Crysis Warhead (was getting around 20fps avg on the highest detail settings). Recently I got my hands on a second HD4890 from a friend for free and have crossfired it. Testing with Crysis shows a big improvement with fps going up to just under 40 avg at highest detail settings. As other games were playing fine before its hard to notice much difference. I game at 1920x1080 so I guess if I moved to a high res monitor it would show(I'm not planning on buying a new monitor though). Just wanted to know how other people got on with crossfire and whether they think its worth it. Despite my second card costing me nothing the jump in power used is a lot. It seems a bit of a waste having a second gpu just eating electricity if I'm not really seeing any benefit from it. Any thoughts welcome.
