Benchmark Results: Audio/Video Encoding
We’ve heard that the added system overhead of additional graphics cards will hurt overall system performance, so we ran our remaining benchmark suite on both 3-way and 2-way SLI configurations.
Audio encoding benchmarks heavily favor CPU performance, while video encoding also places a huge demand on memory speed and capacity. We see zero gains when moving from three GTX 260 Core 216 graphics cards to two GTX 280 cards, proving that system overhead is not a valid reason to criticize 3-way SLI.
I thought that the only problem was that one of the builds performed less than the last one at the same price point. But then again I am used to the comments section of such articles being full of whinners and idiots so its not much of a surprise...
285 SLI is looking interesting
This was a good review, it pointed out to us that buying 3 260s is not so beneficial, Crysis is a great game, but it is not the deciding factor for the purchase of my next video card.
If I really want SLI I would choose as fewer cards as possible. The driver mess and inefficient scaling makes no sense to get more than two cards. GTX 295 > GTX 280 x2 > GTX 260 x3 > 9800GT x4.
Better to notice the fact the 280x2 consistently beats the 260x3 except in the one game that sets the standards for erratic performance results.
