Really, unless you're upgrading your computer every 1 - 1.5 years, buying over-engineered kit can sometimes be worthwhile. While no, most people aren't going to use all of it's features right away, chances are that in two years, programs will have increased in complexity to demand more of what an "over-engineered piece of kit" offers. I'm not saying I do this personally, but I will at least give people who do this the benefit of the doubt. Those that buy the latest and greatest thing every 3 months however will still incur the wrath of my sarcasm (but I will secretly be thanking you for funding the R&D of tech companies everywhere...)
I owned a lightning card. It ran hot as hell stock and never could get a decent over clock on it. It was also the loudest card I ever owned. This whole line fails for the "average" user so to speak and I've read other articles where "pros" can't get decent over clocks. Nifty name lousy results. Just like RipJaws memory.

I think it's me being tired but could someone point out the 6+1+1 design on the card please?
I see the words but I can't recall what to look for on the card itself.
yeah used to go with the crazy aftermarket coolers but like bums said- it dumps heat back into the case = more fans to remove it from the airflow to the cpu.. this doesn't matter to someone who doesn't oc on air, but those that do.. you know after extended gaming sessions, if your case isn't configured right you can say bye the benefits of the aftermarket sink
I still think ducting with a single gpu system on the reference cooler (after you redo the tim).. you can get some good temperatures that way without all the case airflow issues- downside is you can't sli as the duct takes up the area underneath.. I actually went with the zotac 460 the other day because they added a displayport
know ati does this too but I couldn't get a awesome deal like on the 460 1gb.. I could feel huang slinging his dingaling around when I bought it.. I feel like such a toolbag for buying nvidia- especially when ati/amd are coming out with the new cards soon but was under 200 bucks- expect to get around 900 clock so it should be around a 5870 performance when done hopefully
yes I am an nvidiot sellout who knows better.. wish the 5870 was cheaper- kind of an impulse buy lol
Where did you get the diagram which indicates where the power is allocated? Moreover, do you know of a site that has chip schematics like this? I am a computer engineering student at UT and I'm just trying to learn myself some good ol knowledge!

If author looks closer on PWM chip and Driver IC spec, he will see the PWM is up6225 which is 12 Phase PWM chip, and advanced Driver IC is specially designed for pushing 2 phase with 1 chip. N480GTX Lightning GPU is 12 phase with no doubt. MSI will never use parallel connection power design on Lightning, and there is NO WAY to hit 1400MHz+ under extreme OC if MSI use parallel connection, MOSFET will simply blow up because of unbalanced loading.
These six told me a different story on the back of the PCB, although if I'm wrong feel free to email or phone me and explain, then ill update the article. ;)
I don't think the heatsink mount is a problem tbh. It looks to me like it's mounted to the backplate, which in turn has mounts spread all over the PCB. Looks like the load would be spread quite evenly.

It's not mounted to the backplate I'm afraid, they are just holes.

The drive is up6282 (http://www.upi-semi.com/Product/ProductList.aspx?ArchID=86) , it's dual phase mosfet driver WITHOUT phase extension function, so you can think it's two traditional single phase MOSFETs packing into single chip. There are too many components on power design of lightning, using more expensive dual phase drive ic can reduce space.

ReplySweet Jaysus!
This has also given me an idea for an invetion...
A GTX480 that's actually, well, decently cooled WOULD be nice.
Howcome NVidia isn't adressing the ridiculous heat and power numbers of the GTX480?
Please wipe the back-plate of the card with a alcohol cloth before taking pictures.
This is what I mean: http://images.bit-tech.net/content_images/2010/09/msi-n480gtx-lightning-preview/n480gtx-lightning-3.jpg

That looks just awfull *Meh*
See what happens when you rely on spell-checkers to find errors... :D

I got it direct from MSI.

Now, when are the benchies coming Bindi? :D
