I have a costum computer which is built around 700$. I have a Asus Eah2600xt 512 mb graphics card installed right now and looking foward to upgrading to something good around 250$. I am unable to decide between hd 5770 and hd 4890.Beacause 4890 has 256 bit memory bus and the other has 128 bit one but 5770 has 1 GHz more Memory Clock. Does the 1ghz memory clock difference or 2x memory bus difference count?

To recommend you an appropriate graphics card we need to know:

(1) Games you play and at what resolution/settings
(2) Total system settings (specifically: processor, power supply, memory)
