The Card & Bundle

Leadtek kicks off with a deviation from the stock heatsink. Sort of. It looks different, alright, with an aluminum shroud over the exhaust end of the card, and a smaller shroud cooling and concealing the power regulation hardware. But underneath, the heatsink is identical to the stock 8800GTS 640MB model. In use, this modified shroud sounds no different, and certainly doesn't hamper the cooling ability of the whole assembly.

Everything under the heatsink is normal, too. The core and memory clock speeds are stock, the power-regulation bits and memory are all where they're supposed to be, the SLI power plug sticks out the back, and the SLI bridge connector is at the top edge. Without the heatsink, the card would be indistinguishable from almost any other 8800GTS 640MB.

The stock-ness of the card isn't good or bad, but I wonder why Leadtek went out of their way to make the heatsink look pretty without also deviating from the green PCB? It looks a little out of place. But it does make the card cheaper to make.

The 8800GTS comes with your DVI-to-VGA adapter, a TV-out cable (S-Video and component), and a 4-pin-Molex-to-SLI-power adapter. It also comes with a dated driver CD, a manual, some free software of unmemorable function, and a copy of SpellForce 2, a game I had not previously heard of. (Which doesn't make it bad, just. . .I dunno, maybe they could drop the price another five bucks and not include it. That would make more people happy, I'm sure.)

The card also supports HDCP over DVI.

Let's mention what this card doesn't have: hardware video acceleration. The 8800-series video cards were made before, it seems, NVIDIA cared to put forth the effort to have good DVD and HD playback. It's pretty good, but nowhere near perfect. Unfortunately, there are no video cards that offer the kind of gaming performance the 8800GTS does, with superior video acceleration. Even ATI's HD 2900 XT, the mirror of the 8800GTS 640MB, plays video about the same.

looks like the hood off a 70s trans-am.

I just received an identical card today (a Leadtek 8800GTS with the blue heatsink cover).

I've put it through its paces and am absolutely staggered by how high it overclocks. Yours was good, but mine is staggering.

Using the latest 162.18 drivers, it is rock solid with nTune used to raise the settings from the default 513/792 (near as dammit to the 500/800 stock speeds the card is advertised as having). Now I'd expect to be able to raise the core by quite a bit, and indeed I did, but memory is always limited by the speed of the chips used on the card, and whether you are lucky (and with ten memory chips on an 8800GTS, you can't hope for too much).

I was amazed. The core passed 550 easily. 600 as well. At that point I decided to let ATITool do my overclocking and I'd hit Abort as soon as I saw a problem. 600 passed without a problem again, as did 650. It was only somewhere soon after 670 that some corruption appeared, though it was minor and was able to stop ATITool immediately.

I then reset the core to default and decided to see what the memory could do. From the default of around 800, it passed 850, 900, 950 (at this point I was worried it wasn't testing it properly as this seemed a very high memory overclock), 1000, soon after which I paniced and hit the Abort as I feared damaging my card. As it turned out after running other tests, 1000 was pretty much the stable maximum for the card.

After determining safe speeds (650 core, 1000 memory) I've ran intensive tests and it is rock solid on my system (X2 4400+ @ 2.5GHz), with the following 3DMark06 results

default- 8330 (3894 sm2.0, 3751 HDR/sm3.0, 1929 cpu) @ 513/792d (162.18 driver)
default- 8953 (4223 sm2.0, 4207 HDR/sm3.0, 1933 cpu) @ 650/792d (162.18 driver)
default- 8540 (3965 sm2.0, 3941 HDR/sm3.0, 1930 cpu) @ 513/1000d (162.18 driver)
default- 9092 (4257 sm2.0, 4355 HDR/sm3.0, 1933 cpu) @ 650/1000d (162.18 driver)

1600x1200 4xAA(0), Aniso(16)- 5548 (2494 sm2.0, 2064 HDR/sm3.0, 1932 cpu) @ 513/792d (162.18 driver)
1600x1200 4xAA(0), Aniso(16)- 6224 (2912 sm2.0, 2339 HDR/sm3.0, 1926 cpu) @ 650/792d (162.18 driver)
1600x1200 4xAA(0), Aniso(16)- 5869 (2623 sm2.0, 2260 HDR/sm3.0, 1929 cpu) @ 513/1000d (162.18 driver)
1600x1200 4xAA(0), Aniso(16)- 6715 (3156 sm2.0, 2613 HDR/sm3.0, 1931 cpu) @ 650/1000d (162.18 driver)

The 650/1000 doesn't make it an 8800GTX because of the fewer enabled shaders and memory-bus width, but the 650MHz is pretty staggering imo as it is above the stock speed of even an 8800 Ultra (612MHz). I think I've probably been lucky to receive an 8800GTS which clocks as high both in core and memory as it does, but even if it didn't, I would agree with your review that the Leadteks are damn good cards as they are amongst the cheapest.

It pretty much answered my suspicions about factory overclocked cards. That they won't be able to overclock any higher than a random sample from a company which doesn't cherry-pick cores for higher-priced overclocked models.

Nice overclock... Have you tried running a few real games to verify that there are no artifacts? I noticed back when I did the video card reviews that often times you wouldn't see artifacts necessarily in 3DMark but you would in real games.

If you have... congrats on a great buy! :-D

I'm looking to purchase a video card, and thanks to the reviews you guys have submitted I have made my decision to buy this card. Thanks heaps!!
