Gigabyte X58A-UD9 and GTX480 Quad Sli Review
Out of the synthetic and into the real-world, the results pretty much echo our previous page, but generally the fourth card has a negative impact if anything. So we'll whip through them to save you reading the same thing lots of times, and also because this a UD9 review and not strictly a Quad-SLI review.
That fourth card gives us a 4 frame drop in Dirt 2. The overheads it causes aren't able to be overcome by the power it provides.
Just Cause 2
When it first was released it appeared to be a hardware eater. A couple of driver upgrades and some heavy-hitting hardware later and it's getting spanked. Tri-SLI giving us 164fps. The UD9 has all the graphics bandwidth you could ever need.
As hardware improved we edged towards the 60fps barrier in Crysis Warhead. With the release of the 5870, and latterly the GTX480, we've blown past that and discovered what we knew all along. The Crysis engine is terrible. 16 fps increase for another £1200 worth of graphics card is useless.
