Dual 7900 GTs or one 7900 GTX?

Would it be worth it to spend like another $50 and get two 7900 GTs for SLI or spend $50 less and get one 7900 GTX? One on one, the 7900 GTX is by far more powerful, but wouldn't two GTs surpass the GTX?

You would be better off getting a single X1900XT.

As for your question, yes SLI 7900 GT is better then a single 7900GTX.

As you said, yes two 7900GTs would outperform the 7900GTX, and would even outperform an X1900 XTX, but the difference in price, performance in features make it a bad idea to pick something over the X1900.

x1900xt or 7900gtx, Either one is very good.

"but wouldn't two GTs surpass the GTX?"

Indeed it would, and does, albeit at the expense of using high quality settings vs. the ultra high the 512 mb cards are capable of...

actually Dual 7900GT will surpass single X1900XTX and 7900GTX ..

so If you want to squeeze more perofrmance ..get 2X 7900GT SLI .

Get 1 7900GTX. It will handle anything the current games can throw at it.


I run Oblivion at Max settings and never have any lag.


EQ2 lags though at max settings because their engine is a POS! :) 



Soooo...

Get 1 7900GTX and wait until Jan when the DX10 cards come out and Ebay your 7900GTX and buy 1 or 2 DX10 Vid cards.


Thats my plan anyhow... the choice is yours.

2X 7900gt can easily outperform the 7900gtx with ease. There is no point getting the 7900gtx. If you know how, overclock the 7900gt into 7900gtx clock speeds! Overclock both 7900gt's and you'll basicaly be running 2x 7900gtx :D  Now the 7900 series have different architecture than the x1900 series cards. it all varies on what games you will be playing. Some games take advantage of the Architecture og Nvidia cards. while other games, like Oblivion, take advantage of the architecutre of Ati card, oblivion tends to perfer more of the 48 shader ready architecture of the ati cards. The 7900gt is basicaly the same card as the 7900GTX, It just needs to be unleashed first. both 7900series and x1900 series are good cards You cant go wrong w/ nethier. The nvidia cards seems to have more oc potential than the ati cards, due to that the nvidia cards have smaller silicon chips than those of the ati cards, Whilst the ati card have much better IQ. So in the end, it all depend what you like.

Are you suggesting that the 7900GTX will be worth more when DX10 comes out? There's no way you'll be able to sell a 7900GTX on Ebay and buy two DX10 cards with the money.

SLI/Crossfire solutions can be powerful, but there are two problems with them:

1. They do not scale constantly with every game. Some games you'll get 150% of the performance of a single card, some games you'll get 5%

2. It is not really cost effective as you never get 200% of the performance with two cards.


So, SLI/Crossfire are only really viable in two situations: if you have too much money, or if you refuse to game at anything but uber-high resolutions and settings (where the advantage of SLI/Xfire come into play)

Personally, I wouldn't get a dual card setup when the X1900 XT and 7900 GTX are so damn good. But it's really a personal choice.
April 10, 2006 2:56:13 PM

OMG, dude. That's really bad advice, IMO. Is it worth the hassle and heat of SLI for like 0-5% improvement? If you remember, the 7900 GT is a 7800 GTX performance wise. And, the 7900 GTX is like 2 7800 GTs...

The difference between 7800 GT and GTX was pretty negligible.

Another thing to consider is that buying 2 cards is harder to sell than 1. Believe I've been down this path... (last year I had evga 7800 GT CO SLI)

I bought an x1900xt for $450 and easily OCed it to XTX speeds. In fact I flashed the bios to XTX.

I'd stay with 1 high end card and then get a DX10 card when it's out.

Ummmm of course not... 8O


Im saying, get 1 DX9 vid card because the DX10 vid cards will be out soon and your throwing away alot of money getting 2 DX9 vid cards when DX10 is only 9 months away.

Im saying sell the 7900GTX for $200 or whatever you can get (Double Lifetime warranty) and use the money toward the DX10 vid cards.


Your choices are 1 7900GTX or wait for the DX10 video cards. Its a waste of money right now to get 2 DX9 video cards when 1 DX9 video card will run every game out right now and within the next 9 months at max settings with no performance loss.


SLI fanboys just like to post high numbers on 3DMARK. Trust me, the 2 weeks you will spend gloating about your UBER 3DMARK scores is not worth the extra expence.

As you waste 1000$ on an FX60.

Not only does it make sense to wait for DX10 cards, the difference in performance between at 7900gt and a 7900gtx as well as the difference between 1900xt and a 1900xtx is just not near enough to justify the extra cost. If you want to save money, OC the 7900GT (one), if quality is more important, OC the 1900XT. Don't bother with either the GTX or the XTX, save the extra cash for DX10. If you NEED sli, I guess that nothing REASONABLE I have to say would matter, However, the power requirements for two 1900xt's are signaficantly more than two 7900gt's. Good luck.

Dont be a hater. Just because you cant afford an FX60 :p 



The FX60 will over clock better than an opteron and the X2 4800.

Yes, the opteron and X2 4800 can OC to FX60 speeds.. Yay for opteron and the 4800...

The FX60 can OC well beyond what a opteron or 4800 can do with stock cooling.



Aside from that, my STOCK FX60 is completey Vista ready and will carry be for at least 4 years. Your OCed opteron or 4800 will be dead in 1 year, maybe 2 due to OCing.


All my hardware is Vista ready except my Video card. Thats why I only got 1. When Vista and DX10 releases I will go SLI with 2 DX10 Video cards and ride the wave.

Ohh and I missed this point. How much is the 4800? $600? $700?


and how much did you pay for that extra Video card? $400? $500?


Your system costs more than mine. Post your 3DMARK scores. Id love to compare. :)
