SLi from a financial perspective

Posted this in the wrong forum last night, hopefully this will work.

OK, so I've been doing some thinking about this SLi business, and it seems to me that unless Nividia and ATI are going to start making cards in pairs, there is no advantage to SLi from a financial standpoint.

Lets pretned you have a true SLi MOBO that plays both cards at PCIe X16, well you paid a bunch of cash up front for that SLi MOBO, then I'm guessing people are picking up 1 card to start an a second one later once it is cheaper and they need it.

But the thing is if you didn't get an SLi mobo, you could have put that money you saved it in the bank, and in a year combine it with the money you were going to spend on the 2nd video card, and buy a new video card that is as nice as the two old ones combined running SLi.

What helped end this debate for me was looking at the charts and then finding the costs of two 6800's and an SLi MOBO, VS one 7800 and a non SLi MOBO and then looking at these performance charts:

http://www.tomshardware.com/2005/12/02/vga_charts_viii/page11.html

The rig used by Toms was the only True SLi MOBO out there right now:
ASUS A8N32-SLI Deluxe Socket 939

Man if instead of paying $229 you pay $129 for a non SLi MOBO you can go from a 6800 GS to a 7800 GT and still have $20 in your pocket.

Geforce 6800GS XFX $205
eVGA Geforce 7800GT $285

So unless you are running two 7800's, I can't see the reason for someone to get an Sli MOBO. But I hoping you guys can help me learn more.

I guess if you want to put it into a cost vs performance perspective your argument is true. Thats not why people get SLI though. They mainly get it so they can get the extra performance of two cards over one card. This performance varies widely but it seems to average 25%-40% overall now although some benchmarks show less and some show more. For the person thats counting his/her pennies then SLI isnt ideal. But the person wanting that extra performance isnt usually concerned about cost vs performance. his ideal is more performance no matter the cost.

There's also some debate about wether a dual card setup will stay viable longer than a single card setup before an video upgrade is necessary. I think its a bit too early to make a clear call on that particular debate still. You'd think with two cards you'd have a bit longer but with technology changing so fast at times its really hard to say.

Yep-makes no cents financially. Could even save more $- Chaintech Nf4 Ultra- $68
Connect 3D GTO- $149(with $25 MIR)

=$220 and 6250 3D Mark 05 score(vid card O/C'ed to 580/550)
