the evga has different pcb, that's why i'm thinking about it...(pirate)

I thought the only difference was different cooler.

i compared the card shot from newegg with my 7900GT, they are different..

I just compared both cards, thier the same.

The cooler is the only differnet thing, I'm comparing the pic in Signature series here at Nvnews and a reference 7900GT pic, same card different cooler.

Plus I woudln't change your BFG for it, buy a Zalman 900Cu slap it on the BFG and enjoy have heatsink on your RAM and a much better cooler.

The signature series has more voltage in 3D mode...that's why it can go 600MHz...
and if you look at the back of the card, you'll found more components are soldered on, unlike reference 7900GT.

;) Plus You also get the Signature Benefits, Heck, the free game is worth an fifty $ right there, plus the Tier 3 Level phone support, the lifetime warranty, not to mention it is just a Blazing fast ass card.:D I'd like to see them sell "Matched Pairs" for SLI.(nana2)

For the end user support alone I think it is worth it. Go for it!

I looked at the pic of both cards, all components are the same, they may be running some more voltage to the card (I don't know). Even EVGA's site only claims better cooler and more rigourous tested card. Its a cherry picked card.

Hell ya it's worth it, well I dunno for sure yet, got mine coming Thurs to replace this 7900 GT CO Superclock. I know it's not much faster than what I already got, but given that I upgraded to this 7900GT for free (sold my 7800GTX for $371) then I'd say it's probably gonna be worth it, plus I'll get a free game and support if needed. Gonna pwn j00!

I just wanna know for sure that technically what's the difference(s) of 7900GT signature series.

And what have done to make the core can run above 600MHz.

I guess I know the memory timing is loosened so it can run 1.6GHz.

They don't have to do anything to the memory for it to run just 1600 ,I have two 7900GT ko and the memory on them with no volt mods will run 1900 on one and 1850 on the other and they probally raised the GPU voltage to 1.3 to get it to run 600.

How in the hell can you overclock the memory by 250-300Mhz? Please explain how you did it?

AFAIK, all reference 7900GT PCBs have over voltage protection.
That means the vcore cannot go above 1.29V as 1.2V default setting.

People tried changing voltage in BIOS and was no success.

That's why I'm asking what's the differences that enable the 600+ core.

do in coolbits.

1600 basically is 800 in coolbits.

I'm having mine BFG running 860 so that's 1720.

Well ya I know that, but most I can ever get is maybe 50Mhz overclocks on memory on any card I've ever owned, what I'm asking is how can one overclock by such a huge amount?

Well, honestly, if I had the extra cash, I'd get two of them and sell my 7900 GT CO Superclock, just because that is how I am. Is it worth it? Dunno. Doubt you'll tell any real difference in performance. I plan on putting a Zalman VF900CU with OCZ ram sinks on it for my cooling, that or the Thermaltake Tide Water, can't decide.

Back to subject; If you have the money and can do it, then that is up to you. Your choice. I think with all the benefits it has and just the whole package in general makes it worth it. IMHO.

if u look closely on the back of the pcb on the signature series.. it has extra stuff soldered on it.

I also noticed one of the 3 ICs on the bottom left corner of the card are different.

My BFG 7900GT is just like signature series without extra components soldered on.
