Possibly for a reason. Only scores a 2051 on XIV according to this link.

300 euros? Ouch. Hmm. That's about £250, yeah? Okay, you're being ripped off. The best GTX 460 you can get is the Gigabyte 1GB, and that's less than 300 euros, surely?. You can get a 768MB GTX 460 for less than £120 over here, too, so that's what... 140 or so euros? Not a bad price for a good card.

EDIT: Useful link for assessing just where a graphics card stands in relation to the minimum spec... but keep in mind that some cards have variations, of course, such as the 512MB/768MB/1GB/2GB or DDR3 / DDR5 etc.
