here we go,
1st: don't mixed up with 4870 system you use,
I just clean install whole OS and driver, untouch any tweak at all, and I pop it 3d03 with pure os ,
and I got this, not amazing that much, but @ default on the card, this should be ok score already;)
did some adjustment on system and OC card to 800/925(gddr5 is really hard to oc a lot...:()
and got this..not bad huh?
