I bought new parts today to upgrade my current system, I've spent over $2000 on this rig now and god knows why. I even bought something for the girlfriend so she doesn't criticize me on the money I spent on a computer, PLUS I need to be alive and uninjured when I try out these babies, I needs to distrax tha beast. Corsair HX-620 620W Power Supply - $169 AUD HIS Hightech Radeon HD4850 IceQ 4 Turbo 512MB - $248 AUD BenQ E2200HD 22in Widescreen LCD Monitor (For the girlfriend) - $255 AUD Will yet be giving another user review about the crossfire HIS 4850 512mb with accelero and the other with the IceQ 4 cooler. I'm not quite sure how much I'd be able to overclock with the new PSU I'm getting. three 12V rails (18A on each rail) seems enough for 3.6ghz clock on a q6600 and 2 OC'd 4850's I think... I'm excited for the 4850 crossfire! for sure! despite games lacking crossfire support, the potential it has for the future is more than enough for me to be ok with it.
