    Well for me its not compelling enough at the limited 1280x1024 resolution I play at. I'll stick with my 7800GT.

    I'm guessing it's too early for performance comparisons against ATI's lineup with the new 6.3 Cat, but I'm guessing those with an X1800XT are sitting smugly in there chairs about now.....

    Yes, since I got mine on Tuesday, I'm sitting very smugly.

    Well I am happy with my X1800XT 512.

    It plays everything I want to play on it maxed out which is what is important for me (not a huge benchmark fan).

    The X1800XT 512 seems to beat the 7900GT at the res I play at (1280x1024) and its still cheaper.

    I'm on a 7800GT and probably will stick to it, the only worthy performance increase I will get is if I upgrade to ATi's 1900 series or a 7900GTX, the 7900GT is although cheaper - only as good as the GeForce 7800GTX.

    Very happy, although I was never really expecting the 7900's to blow the ATI's out the water. Looks like, as expected, it takes the win in some things and losses in another. Overall the 7900 seem slightly better performance wise, but a few reviews have mentioned IQ issues, especially shimmering.

    At 1280x1024 I will be siting smuggly until either company increases IQ drastically or add new features....

    Looks to me like the X1900 series benefits from two things over the 7900 :-

    More features which may show benefits in the future and much better value.

    PowerColor ATI Radeon X1900 XT 512MB GDDR3 AVIVO TV-Out/Dual DVI 269.95+VAT

    BFG GeForce 7900 GTX OC 512MB GDDR3 VIVO TV-Out/Dual DVI (PCI-Express) 369.95+VAT ...

    Given the two are much of a muchness in performance terms it's uterly pointless going for a 7900.

    After reading the various 7900 series benchmarks/reviews (and knowing my system outperforms stock 7800GTX SLI setups), im confident and happy enough with my current system (2x7800GT 512MB cards) to last me till Vista/DX10/G80.

    The performance increase is nowhere near what the hype had people believe, ATI owners are in a very nice position performance wise, as the benchmarks seem to show (as usual) that directx is dominated by ATI, and OGL by Nvidia.

    As tempting as new hardware usually is to myself, upgrading now would be both unjustified, and majoritavely pointless.

    Only looks to be 5% more for 7900GTX512 vs 7800GTX512. If you extreme OC a 7800GTX512 it will probably beat 7900GTX512 as it appears to have slightly faster DDR3 @ stock by 100Mhz (although core clock on 7900GTX is 100-150Mhz faster).

    If you already have either X1800/X1900,7800GTX256,7800GTX512, SLI or Xfire little point in upgrading until DX10 cards came out later this year and already nowhere near enough games to even take advantage of DX9+SM3 so not much point getting another DX9 card when they will be upgraded to DX10 in Q4 06.

    Best to wait until Conroe arrives as that looks like it can keep up with SLI/Xfire so by then 60FPS + full AA + full AF + HDR + SM4.0 + 1600x1200 or higher should be reality.

    The new 7900's are just a refresh, they're not meant to be groundbreaking. The 7900gt will end up being very good value i think, especially when some 3rd party cooler are available for it.

    Yeap guess the estimates of 10% increase were right, ill stick with my 512 GTX, dont reckon its worth many people upgrading especially if u got a GTX/X1800XT+ either.

    Its better to wait this summer/fall for ATI/Nvidias next gen beast should fit in perfectly for DX10-Vista brigade.

    For me i think id rather get another 7800GT to SLi with my current one instead of a single 7900GT.

    The main thing with the 7900s is that they are a lot smaller the ccores, only 278million trannies vs ATis 364million and only 196mm^2- smaller than the R430 core! This means that they are very cheap to make with very high yields, they don't need much much and so run very cool, and therefore are very quite when properly cooled. Because they are cheaperto make and have high yields Nvidia can charge less and still make more profit. Yes, we may be suffering from rip-off e-vendor hype rpices but when prices settle down ATI cannot match Nvidia's pricing without loose a lrage profit margin. In a price war, ATI just wouldn't keep up.

    Hence Nvidia's tactic.
    The real deal with these card is the affordable SLI. When the 7900GT SLI appear for $600 that card will massacre ATI's sales really.

    At the very least any ATI fanboyrs can thank Nvidia to be the first to realise that prices needed to be lowered and also that quite and cool chips are important. One thing rings clear from all reviews, the X1900 runs very hot, uses lots of power and is very noisey. Not seen a single review that says anything other than that (albet I've only seen 4-5).

    In the end you have a card that is cooler, quiter, less power hungary, faster and ultimitely cheaper.

    I think the point here is that the 7900GT will be super overclockable by looking at the other cards in the range.

    And with an after market cooler and some heatsinks on the ram run at super speeds.

    After all they are the same card the 7900 GT and GTX just the GT has 256mb ram.

    The XFX GeForce 7900 GT XXX Edition running at 560MHz
    256MB GDDR3 Extreme Memory running at 1650MHz this has faster memory that some of the 7900 GTX's

    So I would think that the other GT's would be overclockable to those speeds.And if they do would offer massive bang for buck.

    IQ is always talked about,
    here is a review which backs up what I have said all along with regards to AA quality:

    Pretty clear win for Nvidia IQ wise!

    Just picked up a nice spanking new XFX 7900GT XXX edition card, 560MHz core, 1650MHz RAM, at the low low cost of £205.34 + VAT :D

    Will install it when I get home, run some benches against my X850XT and my BFG 7800GT OC see how it compares, also very interested in how this will overclock by the look of things I think the memory will go to 1800MHz, need to check the part code but it looks to be 1.1ns RAM :D Now I have a Zalman VF770 Fata1ty so I'll bench it and OC it with the stock HSF and no Ramsinks then OC It, change over the HSF for the Zalman and do the same see how cool these cores run really.

    Will get some screenies uploaded at some point tomorrow.

    I have owned one and can confirm this, it's a really high pitched whine which just gets louder and louder as the GPU gets hotter and hotter, even idle in windows there is a definite high pitched whine.

    After a few hours use I couldn't go back to my previous 7800GTX256 quick enough (which i was planning to sell).

    can hardly charge more for a card that doesn't beat the current batch can they???

    would be a different story if they were convincingly thrashing the ati 1900xtx £550 anyone :rolleyes:

    Absolutely! I've just seen that article and the Nvidia's IQ is definitely superior to ati's. Astounding evidence really :)

    egt, do nV actually pay you? If not, then why do you persist? One game cannot prove anything astoundingly - nor does any user opinion - it's entirely subjective.
