Dual Graphics card build?

post #1 of 16
Thread Starter 
What would the benefits of having two Graphics cards in 100% gaming comp.
Hoping its FPS.
Been thinking of going that direction with my new build I'm trying to piece together. Really thinking of 2 GTX 460's.

Any input?

Thanks,
-Karl

Well if you have two options, 1.)Single card 2.)Two cards that equal the single card's performance, you want to go single card for several resasons.

1. Drivers, ati doesn't usualy have the best crossfire drivers for certian games (some will flame me for this)

2. Lack of compatibility in games, I know quite a few games that either won't show any improvement from single card, to crossfire, or won't even run

3. Heat, they're will probably be more heat produced by dual cards, than a single card, although sometimes this is not the case.

4. More power consumption, again, this is not always the case.

5. They take up more PCI-E slots, so maybe you won't have room to put in a say, sound card, or tv tuner.

6. Expandability, once you have dual cards, and you want to add another, you probably won't get even close to as much performance increase you did, as when you went added a second card, ie scale-ability. Although sometimes, (like with the GTX 480) the third card actualy scales very nicely. When you add a second card to a gtx 480, you almost get 100% more performance, and when you add a third card, you get almost another 60% or so on top of that original 100%. This happens more in nvidia cards.

Thats about it for the cons, for the pros of having dual cards,

1. Multimonitor support, ati already supports eyefinity with one card, but if you're going for nvidia, then you can use surround.

2. Cheaper, the gtx 460 sli was a great hit around here a few mothes ago. People would buy them like hot cakes because they were cheaper than a gtx 480, but they performed better than the gtx 480.

I would just get a single.

The advantages, in games that are properly optimized for the use of 2 gpus, is awesome.

Even with that being said I personally will always advocated for the single strongest GPU you can afford. Then sell and upgrade it later.

From my research I've found that most games scale to multiple cards quite well (at least newer games and newer cards). I am adding a second 560ti to my rig tomorrow and all the reviews I have read show very impressive scaling performance in every game tested. Two 560's are almost always faster than a single 580. Driver and game support issues did not seem to be a problem in any of the tests.

I didn't know that Crysis 2 has really high system requirements -.-

I'll most likely stay with Nvidia.
Looking at SLI boards they sure vary allot in price.

Go for either an Asus, Gigabyte, or Evga board (I prefer Evga).

First of all, hey, Karl, it's me, Orville from work, LOL!

Second of all, why not go big with this build? Why stop at only two GTX 460s? Are you trying to make your sister giggle?

Go big with:
-Four GTX 580s via 4-Way SLI
-Dual GTX 590s
-Dual HD 6990s

Anyone of the above three is a nice start to a solid gaming, overclocking, and benchmarking rig!

P.S.
See you at work!
