I know this is expensive for a graphics card but this is currently one of the best priced branded GTX 275s around. I ordered one last week and it comes with a Free copy of Far Cry 2 and 3d Mark vantage. Whilst the 4890 is a good deal, most people have nvidia based boards thus making this a good future buy for SLI. Don't forget free delivery with Av forum members etc.
