4870 Crossfire + AMD Phenom II X4 810 @2.6GHz Tags: Radeon CPUs Crossfire Phenom Graphics Product Last response: January 7, 2010 10:16 PM in Graphics & Displays Share Thraken January 7, 2010 9:34:53 PM Hi guys, I've been reading a lot on crossfire and I could really use some advice with regards to my system: GPU: XFX Radeon 4870 XXX 1GHz CPU: AMD Phenom II X4 810 @2.6GHz RAM: 4GB DDR3 @ 1333MHz Motherboard: Gigabyte GA-MA790XT-UD4P 790X Display: 26" TV @ 1360x768 From what I've read, crossfire doesn't see huge gains on low res monitors, and can also cause the CPU to bottleneck. From your experience, would I see much of a boost in performance by adding a second 4870? Would two 4870's bottleneck my CPU? Thanks for the help!

But it's not true at all that you don't see a gain in performance, it's only that the gain is not the best. For example, I was getting 130FPS with my 2 4850 in crossfire at 1280X1024. With a single one it turns around 70 FPS. It depends on the games. If you change your monitor to a 1080p monitor, your second card will really makes a difference. For now I would not buy another one. Still, a 4870 at your resolution is easily able to run Crysis at maximum details without AA... I am right? rolli59 a c 563 à CPUs January 7, 2010 9:45:29 PM A single HD4870 should be able to handle every thing pretty decent at you resolution. Two of them would be slightly bottlenecked by your CPU but you should be able to overclock to compensate. Can't find your answer ? Ask !

Most games run ok on my machine, though not as good as I was expecting. Still, I'm able to run most games at ~medium-high settings. Thanks again! Can't find your answer ? Ask !
