Testing
A single Zotac 8500GT card should be enough for the average Windows XP or Vista user. You can enjoy Vista, watch HD videos and even play some games at lower resolutions. Nevertheless, we wanted to know if two of these cards could get us some playable FPS in higher resolutions, and if it's worth to eventually buy another one and go SLI. We compared Zotac's 8500 GT SLI siblings with an Asus 8600GT card which costs more than one 8500GT, but less than two of them.

The two Zotac 8500GT cards scored 15,032 points in 3DMark 03 which is 46% higher than a single Zotac 8500GT. If we compare SLI results with the reference 8500GT card that got 8,328 points, we can see an 80 per cent performance boost. Nevertheless, "double the fun" with Zotac 8500GT SLI is not enough to win against a single 8600GT which, as we said before, costs less than two of these.

3DMark 05 managed to utilize the additional power of a second Geforce 8500GT, so the SLI system gets a win with 10,628 points. The Geforce 8500GT SLI system is 19 per cent better than the 8600GT and 73 per cent better than a single Zotac Geforce 8500GT card. In any case, the reference 8500GT card, with its 4,725 marks can't be compared with Zotac's 8500GT SLI, it is 124 per cent slower or 5,903 marks.
