Ok, I am interested in getting an SLI Configuration, probably two 6600 GTs, being the most affordable cards I could do that with and I was curious to see if they make any mobos for the Socket 478 Prescott that allow SLI or am I going to have to get the P4 EE to get that? Also, I've not really looked too much into SLI and how it works, but what is the motherboard/graphics card going to need to have? Links to some compatable Pentium boards if you can, thanks!

As far as I Know (although im not positive), there is no SLI s478 motherboard out there. On that note, I would recommend that (unless the only thing you do is play DOOM and run 3dMark) you get a single higher performance card instead of two slower 6600GT's. With the price of the two 6600GT's and the money you save with not having to upgrade your mobo/CPU you could by a seriously kick ass card. Possibly a 7800GT. Even if it was the same price and same amount of trouble, I'd take one card over two anyday. There are even some cases where a single 6600GT outperforms two 6800GT's in SLI. It just isnt that (consistantly) efficient.

WOW is that true or an exaggeration that a single 6600GT can outperform 2 6800GT's? :S

It's true. Its on Tom's Hardware Guide. I'll look it up and edit my post with a link.

Well, its not a link but here are some fps results from Unreal Tournament (attatched). The single 6600GT doesn't outperform the SLI 6800GT's, but it does outperform the SLI 6600GT's. And a single 6800GT outperforms SLI 6800 Ultra's.

I wouldn't, because one game is a statistical outlier. We've seen that the oddball results reported here don't hold up in most cases (SLI gives better performance than no SLI, and the question lies in what the delta is).

For the OP, there is no such thing as an SLI board for S478, but there are examples for LGA775 (MSI P4N Diamond springs to mind).

Why go for a puney 2 card SLI setup when you have have 4 card setup with 8 monitors!

If your going to get SLI for a P4 get the Nforce one for Intel.

SLI does fairly consistently perform higher than a single card, but it seems that if you spend twice as much on a single card as opposed to two cheapers cards, that you generally get better performance. I could be wrong though... I would trust C38368's opinion over mine.

The cheapest SLI capable 6600GT is $139 from newegg, which is a total of $278 for the two cards. For that price, you can get an X850PRO, an X800XL, a dual-GPU (single card) 256MB 6600, or a 6800GT. Not quite sure if any of these would offer better performance, but I would go for the X850PRO or the 6800GT for sure.

That's pretty much true.

Allow me to clarify my thinking: when I wrote my previous post, I was specifically referring to UT2k4, and a single 6800GT doing better than two in SLI. There are cases, especially if you look back to when SLI first went live, where enabling it caused an absurd performance hit, but that's the exception rather than the rule (usually the game just crashes when it doesn't like SLI ;) ).

At any rate, if faced with a choice between a single "better" video card (such as a 6800GT) or two "lesser" video cards (6600GT, say) for SLI, you're usually better served to go with the single better, especially if it's SLI-capable itself.

Sorry for any confusion I caused :)

Has any one seen any benchmarks with Intel motherboreds and AMD motherboreds running SLI?
