Yeah i thought so but i was low on budget and cpu wasn't a big deal for me at first.
Now if i can solve this heat issue before summer. It gets really hot here in Istanbul.
As far as your 3Dmark score goes, if you listed the individual scores (SM2, HDR/SM3, cpu), it would be easier to figure out the problem.
As to the heat issue in Istanbul and changing to a liquid cooling for the video card, Sapphire makes a X1950 Toxic which is factory liquid cooled. It both helps with the cooling and lowers the noise factor. The other possible problem you have is not having a cpu with enough mhz. But without individual scores, its all but impossible to tell where the source of the problem is.
old after market ati coolers ducted out the back they worked great i have on a 850xt - the new one does indeed blow on the mobo i had one on a 1800xtx - i thought it caused the system to shut down but it did not.
i did not like it anyways.
you can get a water cooling systems that will fit in 2 5.25 bays for $70 at new egg and it water cool the koolance cooler ($70 too) nicely
