I have an ATI card that is pretty good. I can't get it to overclock past 790 core though in catalyst. Any ideas? fyi I have the memory set to 1050 when overclocking atm. It can go higher on memory, but I like to keep the core and memory speeds closely matched. Also I'd like to up the voltage to really get the fans going. You see, 6000P in 3DMarkVantage is not working for me atm fyi btw my next system is going to have for gpU's
