Yes it will do better, I think it is the main limit on the system. How much I dunno. A review you might wanna read
HERE and
HERE The second one shows the c/w for the block somewhat lower than JoeCs review. Unfortunaly most manufacturers do not provide much of the needed info on their products and testing is difficult so differant reviews may show completely different numbers due to lack of expertise and or test procedures. I would loose the chipset block, if you want beter cooling there get a MicroCool or similar product. It is not worth the added restriction on the loop.
