Is it true that the 9800 series is just a factory overclocked 9600 with a bigger heatsink? And, prolly not but, if you try to OC it even a little bit it will spark/smoke/explodzorz? My friend told me this and I don't believe him, but he owns a business based on videocard repair/OC etc. Also, what are some good mods for the 9800 pro?
