I am stuck between the 5830, an already overclocked 5770, or anything within that cost field that would give me the best graphics. I heard the 4890 and some of the similarly costing ones can preform better. Also I was wondering what is hybrid crossfire, does it basically take the onboard graphics card and make it help the offboard one. For example a a 4290 and a 5830 (or whatever). Or is it only for that series 4XXX like with regular crossfire.
