We will be testing the 6800 Ultra in SLI mode and in single GPU mode today. What we will be looking at which is something that we haven't seen yet is a few synthetic tests on how and if SLI affects performance of memory or CPU. We will be running the tests through our normal gaming benchmarks which include the 3DMark series as well as Half Life 2 and Doom 3. We will also have a look at what happens when we start bumping up the AA and AF and also finally our normal synthetic line up including SiSoft Sandra and PCMark.


Our Performance PC article #2 will be coming in the very near future so we will be leaving overclocking of these cards till then. For now lets have a look if you could warrant the forking out of those extra dollars for a second 6800 Ultra PCI-E.

3DMark2001 SE is a part of the popular 3DMark series. By combining DirectX 8.1 support with completely new graphics (including the GeForce4), it continues to provide benchmark results that empower you to make informed hardware assessments.




We can see here that SLI doesn't really give a huge jump in performance since 3DMark01 is quite CPU limited these days. We notice an increase when we start to overclock the processor but we will look at that another day.
