Neoseeker takes a look at the ENGTX260 Matrix, from AsusTeK

The Asus ENGTX260 Matrix is like a Porsche 911 Turbo with a engine-limiting chip in it that doesn't allow you to go over 90 MPH. Said another way, if there is only one flaw with this video card, it is that it doesn't take full advantage of itself out of the box, because it defaults to the standard GTX 260 speed, and the "Gaming" iTracker preset overclock is a bit underwhelming.
