Firstly since this is my first visit i would like to say what a great website and thanks for having me.
I recently stumbled across your website and use it as a useful tool as to gage components as i am looking to find a new computer. One computer in particular had a videocard Radeon HD 4890 but recently the sellers have changed this to a Radeon HD 5770. According to the passmark high end chart this is ranked lower than the 4890. This has left me a little confused since the price has also increased somewhat. Can somebody please clarify which is the better card and perhaps elaborate as to why the newer 5770 is lower in the chart.
