    Why call a 955 $255 plus 790GX mb $110 plus 4 gb ram $41 is $500, when it's actually $410 before shipping and rebates, which about cancel out? And that's just picking off the cheapest at newegg and not price shopping, which might knock it below $400.

    Not to mention the six months on the market the other set up has had to drop in price ...

    Fingers crossed for AMD. Intel needs a competitor!

    Of course, even at NewEgg, the i7 is still just a benny more, at $280 for the i7, $84 for 1600 6gb ram and $200 for a MB. What's, $564 before ship and rebates, knock $50 if you get the i7 at microcenter, and another $20 on real cost after nit picking out shipping and rebates ... and settle for 1333 ram ... you're within fifty bucks!!!

    If it wasn't for that Nvidia issue with the i7 ...
    Hell,

    Hell, you can knock seventy off the hundred dollar price diff. with an open box motherboard for one thirty instead of twoo hundred.

    Nice processor, but until the price drop comes the only reason to buy it is if you're upgrading. If you're doing a clean sweep it's the i7 all the way.

    Not fair. Don't compare open box prices to new prices. If you want to buy used/refurb/reconditioned/open box, then compare the prices against the same used/refurb/reconditioned/open box equivalent for the other platform. Otherwise, you are fudging your numbers.

    "The only standout in this clumsy console port is AMD’s Phenom II X3 720, which lags at both 1680x1050 and 1920x1200. The rest of the processors serve up reasonably close performance, per what we’ve come to expect from Grand Theft Auto 4."

    Yeah that whole less than 10% behind the i7 920 is totally lagging and not close in performance... who writes this drivel?

    Yup--any of these games will be fine with a 720 BE and more graphics muscle.
