Looks like it performs very well compared to the standard 7900GTX, but the price is still quite steep and the fact that is supposedly a lower model wouldn't look good for your internet boasting (call it what you want, there is a better way to describe it) I have to say! Still think I would go for an X1800 GTO as a budget card at the moment.

Nice review though W1zz.

nice review

i heard that evga and msi put tighter mem clocks to make up for the lost mhz as best as possible, and thusly, a gto @ 800mhz ram would out do a gtx @ 800 mhz.

i wonder if madmox just oc'ed the ram, or maybe they loosened the timings too? could you post the mad mox bios into the bios thing, w1zz? that'd be sick

Dont see much point in paying the extra tho as mine out of the box overclocks higher, I must have got a lucky one because it gets better with age, can just about do 713/840 now with mine although I have not benched it since I first got it in October, will have to some time!

Also the MSI is the better option over the EVGA as it is HDCP also. Are they really hard to come by now?

I guess it comes down to whether you want to try your luck or pay that little bit extra and be assured of getting a high performer for better value. I haven't had much luck with OCing my cards, admittedly my PSU sucks and I only use stock cooling plus case fans but my cards never OC that high, although my X800 GTO came with all 16 pipes unlocked for some reason . I think it was new...

but even my gto, which oc's worse than most that i've heard about (700/760), will be about the same perf as a stock gtx

however, the stock gto can't be found anywhere, whereas the mad moxx is available. imo, mad mox should have just bought the boatload, and then held onto them for these 3 months, and then sold them. most 7900gto's are going for 290~+ on ebay, so a brand new one would be 300 easy from a retailer.

the only thing i don't like about the mad mox, is that it prolly won't go much higher than 800 anyways. oh well

but i think that what mad moxx does is smart and wouldn't hesitate to buy a product from them if i missed out on a deal like the 7900gtos

Yeah but to put it in perspective, I only paid £150 at launch for mine (they put the prices up the following day!) which is what the 1950pro launched for in the UK and its a fair bit faster, so certainly it is "bang for buck". As fast as a GTX for half the price, cant be bad! I think they are still available in the UK tho.

Not a bad card, but still too damn much money for the pittance of gains. Still, if this is an only option for some, its a good one. ATI has cornered the market on value and power~!

Well as I said, the same price as a 1950Pro and a fair bit faster so really you could say that NVidia have cornered the market not ATi in respect of this sector.

[tkpenalty]

Is this a vain attempt to get back the consumers trust by Nvidia?

W1zzard makes GREAT reviews!

But why make a review for a product that can no longer be bought?

[Tatty_One]

Dunno, the cards are still freely available in the UK still.

Am I the only one that finds it the slightest bit odd that NVidia recalled the cards because they couldn't do 800MHz on the memory. Then NVidia lowers the clock speeds to 690MHz to fix the problem. But, then Mad-Moxx takes them and clocks the memory back to 800MHz and magically they work at that clock speed?

The lower overclocking headroom on the memory kind of scares me. This card might work perfectly fine in a well ventilated case or an open workbench, but something tells me the original problem will show it's ugly head if you try to stick this card in a case with poor airflow.

All they did was lower the voltage to the memory which is why results are sporadic between cards, the MSI cards have the GTX cooler which is excellent for memory cooling and if it cools the GTX's memory upto 900 why would it not cool the GTO's at 800? The 7900GT stocks its memory at the same speed as the GTO and even on it's farty little cooler overclocks to 870 without problems.

Ohhhh and they are not all recalled cards either, if they were there would be a lot more manufacturers than just EVGA and MSi pushing them out as GTO's.

memory really wont have an issue with the heat of poor airflow any air flow (assuming there is some)cool the ram just fine we went over this in another thread

The problem is that the RAM on the original batch couldn't handle the 800Mhz, that is what these cards are are based off of, most likely due to RAM overheating and causing artifacts. The whole issue is that the cards originally couldn't handle the clock speed and were recalled, relabeled, underclocked, and resold. So how are they now working?

Yes, and you said making RAM cooler doesn't increase the ability to overclock it. You are wrong, we told you that. By itself it doesn't increase overclockability. However, it allows increased voltages to be pushed through the memory without it overheating and causing instability.

High voltage+low airflow=Overheated RAM=Instability

The batch of DDR3 on the first batch of 7800GTX cards probably wasn't able to handle the heat generated at the voltage required.

[Tatty_One]

Well that just reinforces the fact that not all GTO's are returned GTX's then as mine has been running all day for 2 months at speeds in excess of 800Mhz without a heat or stability problem......maybe I got lucky. And these cards are just the opposite, they are undervolted therefore no heat issues.
