What do you Reckon? - 2 x 6800GS Sli OR 1 x 7800GT

[Kanavit]

i went the 2x PNY verto geforce 6800 GS sli route.

and loving it!! :twisted: dude, no one can match my 3dmark03 score with single card without cheating.

3dmark2001se: 28705
3dmark03: 23636
3dmark05: 11112
3dmark06: 4866
those scores are overclocked on air stock cooling no volt mods!!

Dude get a 7900 GT, its better than a GTX. Less heat, and sound compared to two 6800 GS's. I mean sli sounds and looks cool, with that little bridge thing connecting it and all that but why have two handguns when you could have one shotgun. You understand what I mean right.

NICE !, But seriously I love 3d marks and stuff but it doesnt mean shi*. And why do people test their cards in like 5 versions of 3d mark. lol, just use the newest version. The 06 version is fine. 2001/3 is really unrelevant because you'll get high scores in that anyways. What i like is that 3d mark 05 and 06 score you got there. Thats about a 7900gt. Rock on, 2 gs's in sli are good enough.

actually the newest 3dmark06 is bS. the processor score accounts to overall score, and gives wrong scores. for example, my 2x 6800 GS could score higher in all the sm 2, sm3, and HDR tests, but lose overall score in a similar system with dual core processor. since the cpu test in 3dmark06 are support dual core processors. my system is still on single core, so i get lower score even though i have higher 3d scores.

but anyway, SLI is here to stay! :twisted:

 

[hashv2f16]

yeah I wouldn't bother too much with SLI right now, or ever. It's a waste of money.

 

[HumbleGod]

I also think that SLi/Xfire is just a money making scheme

Amen. Another brilliant way to get rich off of fools with more money than brains.

 

[hashv2f16]

yeah totally, but it DOES boost your performance to some extent

 

[jrwriter]

well 3d mark scores are really irrelevant. 3d mark benifits the most from SLI, even more than the games do. The truth is 2 6800 gs's will definitely hold up to a 7900GT at lower resolutions. But when you get to 1280, and 1600x1200 youll see the 6800gs's flop like a bad pancake.( believe me, Ive seen the benchmarks) The 7900gts will however hold up at those resolutions. But I guess if you play a mid resolutions then your definitely fine. I like one card though cause of less heat, and noise

 

[raven_87]

Yes, I realize this. However are comparison would be SLI 6800GS against a single 7800GT or GTX. Had it been a 7900 series card in the matter, I obviously wouldnt have bothered.

"Plus, a second 7900 will give you like a 20-30% boost for twice the price! No way, I'm changing my mind, Dual cards suck, SLI and Crossfire."

FEAR is gpu bound even at 1024x768/4xAA/16xAF....

one 7800GT: 49 fps avg (33% of the time between 25-40 fps)
SLI 7800GT: 95 fps avg (90% of the time above 40 fps)

Yes, there are titles with only a 20-30% boost in avg framerates in SLI, but...FEAR is not one of them! 🙂


SLi sucks only in that it is expensive for a pair of 7900GTX cards, but a pair of 7900GT's ($600) will defeat any single card every day of the week, and will frequently even defeat a pair of 1900XT variants in Crossfire....

I don't run SLI, but I think there are some scenarios where it makes sense:

1. For a top of the line gaming rig at high resolutions and settings running two of the latest cards in SLI.

2. As an upgrade path in the future if you can get an SLI motherboard at a small price premium over non-SLI MB.


I don't get where some people say it's not worth the price premium because 2X the cost doesn't equal 2X the speed. I can easily get a CPU that is half the price of an AMD FX-60 that is more than half the performance. That is why a price/performance curve is never a straight line. This is true whether you are talking about CPUs, GPUs or engines in a car.

Proof that SLI isn worth it.

look at HL2: Loast Coast you LOOSE 4 FPS while in SLI mode

 

[Jim_L9]

That just proves that in that one specific configuration playing that specific game it wasn't worth it.

 

[hashv2f16]

4fps? might just be slight fluxuation in the results, because of course you're not going to get the exact same results every time you test. because otherwise, how would SLI actually give you less performance than just one card??

so what do people say SLi isn't worth it for real gaming? well, the benchmarks above proves it is!!!
