    inmytaxiHell, 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.

    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 ...

    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 ...

    "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.

    For budget gamers? If someone is a addict to gaming (aka Gamer), they would probably spend a little more on the CPU and still get a good video card. Of course, on these games, you really dont need anything more than a 720 and a good video card, but there are more hardware intensive games than these.

    Why,

    Crysis is crazy GPU-bound. It doesn't add much useful data to a CPU review--expect to see it back in the graphics story I'm writing right now, though!

    While the 955 was not the whopping jump in performance over the 940 I had hoped it might be, nor is it showing any signs of latching onto the i7's coattails in many regards, it shows a step in the right direction for AMD by finally offering a solid X4 AM3 option to the X3 710 & 720, and the underwhelming X4 810. With AM2+ users able to use any of these processors (mind you, BIOS update usually required), AMD has shown it's continued ability to offer solutions that ease users into another new platform. While that's nice, some may argue they'd rather see huge leaps in performance that require hardware change, rather than smaller performance gains that do not. I find myself on the fence with that one...

    PI think I'll wait to take my AM2+ board into the realm of AM3 CPUs, specifically the 720 or 955, just a little while longer. Mind you, this is despite my X2 5000+ CPU bottleneck and knowing that any of these CPU's would offer a major performance increase. My biggest concern being whether or not the 920 and 940 are the final kings of AM2+, and that the 955 might be the king of AM3 for quite a long time, as well as what else a complete change to AM3 would bring (aside from DDR3).

    I'm also concerned that perhaps in order to catch those i7 coattails (hopefully even surpass) I mentioned earlier, AMD has to give up on their easy transition from socket to socket approach and make a more significant change. Since you can only squeeze so much water out of a sponge before it's dry, I'm curious to know how much more water is left in AMD's AM2/2+/3 easy transition platform(s?) before it goes dry.

    Raz,

    You'd be safe at least through the second half of 2010 (that's as far as the roadmaps shown to Tom's Hardware extend). At least into Q3, you're still looking at AM3.

    phenom 955 Shows its theeth. more importment all 2m+ cpu's are now aproaching bargain prices. 178 euro for 940 here in the netherlands now this was the old 920 price point. hell ye you can build an awsome system with 940 and the radeon 4980 and the samsung t220 for around just below 900 euro now :D forget about i7 you can easily have xfire for the premium on the amd setup. perhaps 2x 4830 might even outweights a sinlge radeon 4890 that should roughly save you about 30-40 euro still need to see some benchmarks tough but AMD provides good competition now and most of all these cpu's might get along wiht I5 as well since I5 is meant to be slower then i7. the diffrence between ph II and i7 920 is just a bare few % now so ph II should be very compatitive with core i5 as well .

    You refer to the Q9550's retail price when comparing but tested the Q9550S

    From the way AMD's looking, if you're worried about a quick socket jump, it ought not be much of a concern... it seems their next major leap in performance, Bulldozer (which I would assume will come with a new socket / platform) won't be out for some time (early 2011 at best), and until then AM3 will likely remain king. Then again, perhaps we'll find ourselves with a consumer version of the 6-core Istanbul that will require a new socket before Bulldozer. Who knows, really.

    Gray - The Q9550 is identical to the Q9550s, save for power consumption. ;)

    Pleaseeeeeeeeee, evolve and drop those ancient WINZIP and WINRAR. Use free open source 7-zip in your benchmark, which is more advanced, multi-threaded, has higher compression ratio.
