What do I need to run 2 9800 GTXs in SLI?

Agreed with also.

I would rather get something like a GTS now (if I was upgrading) then get the best card in a few months time. Otherwise you are buying a few months of splendor, followed by "hey look the G200 is out... hey look its faster than my cards are in SLI :("
 
Yeah, but when the G200s come out they will cost an arm and a leg too...

I think this is the decision I have to make:

get a GTS with a P5N-E mobo and uprade GPU and mobo later on

OR,

get a GX2 with a P5N-T mobo, pay more now, but avoid having to upgrade in the next 3 years or so.

Edit: the current price diff is about £300 btw - I can't decide whether it's worth it (afterall, if I was to SLI 2 GTSs that difference would only be about £150, and I would have to make do with a relatively inferior mobo)

You honestly think a GX2 or an SLI setup is going to be more than a new card? unless you go for the "ZOMG its the best one" card, and go for the 8800 GTS type of card released, it shouldn't be to expensive.

And no card will really last you 3 years without an upgrade really, especially if you play in high res and with the games progressing fast as they are. If the likes of another crysis hits in 18 months, and the engine becomes popular, or other games catch up with even crysis now, even the GX2 will appear slow.

Still, its your money - do as you feel is best :)

your logic is flawed. look at the X1950XTX, and how antique that card is...

second off, i can virtually guarantee that you will want to upgrade with the advent of nehalem, which will be here pretty soon
 
Get an 8800GTX or GTS and upgrade to the new generation of cards which come out in July/August as they will be based on completely new tech. It will be much cheaper and you will thank me in a couple of months.

Thats wrong though, those cards aint completely new tech, they are the 9800's again (which were the old 8800's put onto a smaller 65nm process), but shrunk again to a smaller 55nm process, the next gen GT200's are back end of this year, beginning of next. :)

Why wait till then to buy the cards you can buy now but at dearer prices, just like the 8800 GTS 512mb, that was released again and hiked in price, so you may as well buy them now before Nvidia put the prices up. :p

I just checked wikipedia on the 750i. This is what it states:

nForce 750i

* Codenamed C72P
* Addition of the nForce 200 PCI-E bridge (previously codenamed BR-04)
o Connected to the northbridge via a 4.5 Gbit/s proprietary bus
o Support for PCI-E 2.0 [1]
* SLI
o Slot 1: full speed PCI Express 2.0 x16 slot from nForce 200
o Slot 2: full speed PCI Express 2.0 x8 slot from nForce 200
* Supports a maximum of DDR2-800 dual-channel memory
* Support 1333 MHz FSB

I guess that means it won't SLI properly..

The EVGA 750i F.T.W does full with 16x/16x according to one of the reviews on their site. I'm not sure when it's out though.

Can anyone tell me the answer?
I figured I'd need a decent power supply at 750W or higher, but I guess I'll also need a pretty slick mobo. Will this one do the trick:

I wouldnt skimp on the PSU, particularly for Sli

Only power supplies that pass NVIDIA SLI certification can be called "NVIDIA SLI-Ready certified." Be sure to look for the NVIDIA SLI-Ready badge when you buy your next power supply.

Hello kissenger, what other hardware components does or will your system consists off? :)

Hello Grimley, depending on the other hardware components kissenger system or will consist off, either the corsair hx 620w atx2.2 modular sli compliant psu or the corsair tx 750w atx2.2 sli compliant psu will be absolutely fine for running an dual nvidia 9800 gtx system.

I would just like to point out that the list from the link you have posted is actually recommended power supply units for a dual Nvidia 9800 GX2 graphics card system and not a dual Nvidia 9800GTX system. :)

Yeah confused me to, he says 9800 GTX SLi in the title, but he says 9800 GX2's in his post, so im assuming he is on about quad SLi with 2x GX2's, as i can't see him being daft enough to buy 2x 9800 GTX's to go in SLi at their prices, as the 8800 GTS 512mbs which are the same cards are cheaper, so he may as well pair 2 of those in SLi instead and save some money, if he isn't going GX2 quad. :)

I didn't notice that kissenger was talking about the Nvidia 9800 GX2 in his very first post. I swear it said the Nvidia 9800 GTX when I first looked at the original post. :p

Would you care to clarify for us kissenger please? :)
