It really depends on what you´re using your system for?
Buy in any way, i would recommend u to wait for Ivy Bridge, since it's only 3 weeks away.. I'm also building a new PC and i'm now using pentium 3 untill Ivy Bridge releases.. (i sold my laptop)
Thanks for the reply the reason I went for ATI is because I need the mini display port as I'll be running the Apple Cinema Display with it. - I also want it upgradeable thus why I went with the power supply so that in the future I can maybe buy a second card and X Fire it - I might be waiting for the 7990 at the end of the month... - I want it to be quite future proof but also upgradeable
Also on that note I will prob be waiting for the Ivy B to be released too..
You need to understand a 1200w power supply is meant for quad crossfire systems, you are just throwing your money away with that. Power supplies work most efficiently when they are using at least 80% of what they are rated for, so there is another reason not to buy a 1200w power supply.
