Re: MSI GeForceFX 5900XT to 5900?
By loosing the memory latency, you'll get a chance to overclock a little more. The overclocked frequency is enough to overcome tight memory latency + some more performance. Although Daneel is right, memory is not the bottleneck of FX 59xx Series. My MSI GeForce FX 5900XT (390,700) is almost as fast as my ABIT FX 5900 (400,850). You can only need to do volt mod and throttling.
