This card is the beast of our roundup: The XFX 6600GT Extreme Gamer Edition. XFX is the only vendor that we've seen take a stand and do something different. The first thing to notice is the dual DVI connectors on the board. This isn't normally something one would need on a mid-range solution, but having just come from newegg.com and noticed that the standard XFX card with dual DVI costs less than some PCIe 6600 GT parts without dual DVI, there's no reason to start talking about cost being a huge issue, and thus, no good argument for why dual DVI isn't on these cards.

There is something that this card has for which a premium may be charged: 1.6ns GDDR3 running at 600MHz. We haven't seen pricing yet, but this part is obviously not going to be the "be all, end all" value of graphics cards. Adding memory bandwidth is a good thing for the 6600 GT, considering the 128-bit bus. The problem is that the performance benefit is maybe half the increase in memory bandwidth, if we are lucky. And we might see better scaling with AA enabled, but on a mainstream part, that's pushing the limits.

Anyway, modifying the stock HSF, XFX placed a copper plate between the die and heatsink in order to increase the tension in the spring pegs and keep harder pressure on the GPU. Also, they are doing the same thing that we saw Leadtek do - there is a bit of material around the silicon that acts as a spacer between the rest of the GPU and the heatsink. This is necessary because the copper plate lifted the rubber nubs off the PCB making them ineffective stabilizers.

This card was loud, but cooled well due to their innovative adaptation of the stock cooling solution. The inclusion of 1.6ns GDDR3 will also be very attractive at a default clock speed of 600MHz. But this will not be appealing if it is incredibly higher priced than the current round of 6600 GT products, especially since (whether by design or chance) Sparkle's 6600 GT had 2ns RAM that overclocked to 610MHz as well.

    I've been checking the various forums and found thisone on the 6600gt's excellent. I don't know if anyone else has found them but Asus are making these cards and do a faster than standard model by using faster memory they recon according to their site they run 10% faster than the standard. I've ordered the Asus board by preference because of the build quality Reply

    I came across a forum a few months ago here in Hungary, and the people were talking about Leadtek's 6600GTs being faulty/freezing. Strange enough, a few weeks later, the main distributor of Leadtek, took off 6600GTs from their pricelists on the web. Wonder if they are waiting for a bugfix, or simply ran out of stock and wait for the next shipment.

    Another beauty I've just came across, is Gigabyte's TurboForce edition, which is a slightly overclocked version of the 6600 series (both PCI-Ex and AGP 8x). I'm shopping for a SILENT AGP one, (that's where I came across this review), and found this beauty


    This one has sg. they call Silent-Pipe as a cooler. Not much specs on Gigabyte's page, but from the picture, it looks like there is no fan at all, just a huge copper(-colored?) heatsink, that covers about 2/3rd of the card. (Well, a Zalman FB123 could still be used to move some air)
    The memory clock is wrote to be 1120MHz (remember, TurboForce), plus when I zoomed in on to the box picture, I could spot "VIVO" written on the box. This is also supported by the info on the local dealer's page, where they say "Y" to the TV-OUT of the regular GV-N66T128D, but they say "IN/OUT" for the GV-N66T128VP. All this for roughly 20 USD extra (local price).

    I've bought http://www.giga-byte.com/VGA/Products/Products_GV-...">Gigabyte GV-NX66T128VP (TurboForce, no fan at all)
    Start up temperature 52C, maximum 65C.
    Is that normal?

    I found the article quite informative. Thank you. I purchased two Palit 6600GT cards a week ago and have put them in SLI mode.

    I have a few questions/comments:
    1) The Palit overview is rather short compared to the others. The Palit card is also never mentioned on the last page. Is there a reason for this?
    2) The Palit cards I got DO NOT have memory heatsinks as indicted on the photo for the Palit card. The memory remins cool, however.

    Thanks again for the article.

    Do not go for XFX 6600GT !!!!
    The card is NOT longer equipped with 1.6ns
    The chips on my card are Samsung K4J55323QF-GC20
    THAT MEANS 2.ms !!!

    does anyone know the difference between the Leadtek A6600GT and PX6600GT, besides the PCI-E and AGP?

    I'm looking to purchase a A6600GT, but I don't know if it will have the same performance as the PX version.

    Hello all.

    WOW a great review site.:)

    Just one problem. I was having problems deciding between two of these cards on the ebuyer.co.uk site.

    PNY Verto GeForce 6 6600GT AGP8x £119


    Inno 3D 128MB GeForce 6600 GT 8xAGP TV-Out DVI DirectX9 £116

    This review does not mention the PNY version. although i now notice that they have the LEADTEK at about the same price. Going by these comments i GUESS i should get the LEADTEk??? Anyone know about the PNY cos my mate rekons thats the better one...

    #75: That link to MSI is for the AGP version (note the sink for the bridge chip).

    Not sure if they've fixed the problems with the PCI-E version, and would also like to know.

    Looking at the pictures of the MSI card in the review and the pics at MSI's page it seems that MSI has changed the a lot on their card, including the HSF.

    (Check it out here: http://www.msi.com.tw/program/products/vga/vga/pro...

    Does anyone know if this has solved the HSF mounting problem encountered in the test??
