I have a 9600xt by Powercolor I bought in november. I want to top this card out and see what it's made of. Every mod and overclock possible is fair game. Right now stock cooling I can punchout like 570 core 380 memory. No lockups or anything. This is with 5.3 cats and ATI tool. Looking to push it higher or is this already pretty high? What are you guys getting?
