    LOL its never a good idea to buy a certain card just based on how well it overclocks, let alone how a reviewers sample overclocks...

    AMD Radeon HD7950 Review Dump

    Inside the AMD Radeon HD 7950 is the GPU core, part of the Southern Islands series of cards, known as Tahiti Pro. The XT version in the AMD Radeon HD 7970 is the fully enabled, no missing elements design, whereas the Pro is subtly modified to hit the target performance profile AMD want. Additionally, AMD are allowing Add-In Board (AIB) partners to ship products with customized PCB's from the launch, as happened with certain previous generation Pro variants (6950, 5750, for example). Expect to see some variety of size and cooler for the HD 7950 in the stores.

    TOX has already said why he doesn't use BF3 in reviews. It doesn't have an official benchmark tool so results will vary far too much compared to other sites.

    I don't think they're game to do what techreport do either :lol:

    this is OCAU, why wouldn't it be a factor?

    doesn't OCAU = overly cautious australia?

    I think not having BF3 is a big miss, if you can run it well, then most other games will run with ease except for maybe Metro.

    Because it doesn't mean you will get the same overclocks as a reviewers cherry picked card and i never said it wasn't i factor i said it shouldn't be your deciding factor.

    But hey go for it, plenty more cards to go on the for sale forums :lol:

    If you're going to OC, and you're tossing up between two cards, one that has a reputation to OC better, you're going to pick it.. making it a deciding factor :)

    oooo.... guru3d calculated the 7950 to use about 138W under load on stock frequencies :thumbup:

    nice for ppl with ~450W PSUs

    EDIT: god damn AMD fail at marketing.... still no 7xxx series product info on their website :rolleyes:

    Just on BF3.. you can run through a single player portion to get an idea of performance, and be virtually identical every time.

    which is completely indicative of the performance while you play it with 63 other humans?

    Yeah I think BF3 results are important and are the only results I look at, tox repeated the above about inaccurate results, just look at a few reviews with BF3 results and see how much the results vary .... From slower than 580 to 5 fps faster to 20fps faster ..... Useless numbers.

    :)

    Is a set benchmark that nVidia and AMD can optimise for any better? Though yes I agree multiplayer is generally more stressful on a PC.

    I prefer to see in game runs, all you have to do is work out a run and stick to it, I think most who do BF3 use the part when you are pretty much on rails running through the city from door to door.

    high levels MSAA causes a bigger performance hit in BF3 on AMD cards, so can cause some of the indiscrepencies, FXAA isn't a problem

    Yeah look I wanna know how good it as at bf3 as much as the next guy. If they let you record a timedemo or something else completely repeatable it would be great.

    I like on rails timedemo runs; no human involvement.

    Thats fair, hence why there are so many sites that do reviews. The PCPER review has a video of the run if you're interested.

    no but you can directly compare GPU performance to each other % wise.

    63 humans is also taxing on the CPU..

    Looks like retailers will be getting stock from tommrow, and around $550+ price tag initially with aus-rape-tax

    not quite as bad as the 7970 for new release aus prices, but pretty frustrating still

    i would still like a BF3 test run in every review so at least you get an idea if the game can run on it with various settings -all that has to be said is that results vary due to there being no standard benchmark -hate to buy a card for someone and it run BF3 like a dog
