I have a SAPPHIRE 100245HDMI Radeon HD 4850 512MB and was wondering how much can I overclock it. If I need a good cooler, what should I get?

If your mobo supports it you might want to put the money toward a 2nd 4850 and run in crossfire.

I wish i could buy another one but i don't have anymore money :( . So overclocking is my best bet.

that looks good. I heard something about passive cooling is that any good?

with those speeds, do you see any significant improvements in frame rates?

ok. my monitor is at 1920x1080. I am testing with Furmark 1.8. The MSAA is at 4x, and ran for 30s.

OCd: 875 pts.
Stock:777 pts.

so, i guess a 12.6% improvement. (875-777) = 98, and then 98/777 = 12.6

when the MSAA was increased to 8x, scores were identical. Max temps after those 30s was about 40C.
