I am building a dual Xeon ( 3.06GHZ ) system around an HPxw6000 motherboard but performance will be held back by the onboard rage theatre graphics. The board has no AGP so I'd like to know if anyone has come across a PCIX graphics card. Failing that whats the best PCI graphics card around? I have a secondary dilemma in that the processors I bought were for a rackmount chassis; they came with a passive 1"copper heatsink. I have also bought standard Xeon aluminium heatsinks with fans. I was wondering if I should use the copper blocks with the fan if possible. Thank you in advance for your ideas.
