crossfire & sli

Tempered · #1 05-19-2011, 12:25 AM

With two cards, you could comfortably run a higher resolution, higher AA settings, more eye candy. Two cards does not double your vram.
A single card will probably do you just fine. In fact, sli/crossfire is not supported in all games and is often a waste. COD does not currently support sli or crossfire correctly.

With a Good GPU you can run 1920X1200 with no problems with all the candy on. If you plan to run at the level you posted a single card is fine. Doesn't mean I wouldn't get a motherboard that I could eventually upgrade to SLI/Crossfire though..

thanks, the only advantage I could see at the moment would be to increase vram and crossfire/sli does not do that

getting a motherboard to support it for the future is a good idea though, power supply is another story

My last two rigs have been sli. GTX 460's for the first, and GTX 560 TI's for this one. The only reason I'm still running sli is for redundancy and economics. If one card goes out, I have a backup, and it cost less than a single card with comparable horse power.

If you do go for a single card solution, make sure you get one with 2gigs vram.

palit 560 ti is the only 2 gb card? Is that what your running? are you happy with it? what power supply?

At that resolution you'll be fine running a single GPU. I'd only bother with Dual GPU's if the resolution is above 1920x1200 or you’re running multi 1080i screens.

Come to think of it, a single 6800 or 570+ GPU will do 1920x1200 comfortably.

U do NOT need a card with 2 gigs vram unless u running resolutions above 2000x..... or multiple screens.

Normal res up to (at least) 1920x1200 does not use more than 1 gigs.

It has been tested by every major site and is a fact.(No differance between a, for ex, Gtx580 1,5 Gig and 3,0 Gig)

Yes, I have two of the palit 560 ti's. I got them at a bargain price on newegg.
The only issue I have with them is that the fans can be a bit noisy when ramped up to about 80%, which is as high as they ever go. Also, the card does not properly vent to the outside of the case and some hot air leakage spills into the computer case.

I've had them since about the time they came out (3 months?). And have not had any other issues.

They are somewhat of a gamble, however. Palit seems to be fairly hard to get in touch with if you have any warranty issue.

Power supply is a 1KW silverstone. My resolution is set at 1920x1080 with all graphics on high except ssao and grass. Sli is currently off for COD, but on for ROF which is smooth as silk with all settings maxed.

B.S. on the "you'll never use more than 1GB of vram".

Almost forgot, I did bump the core voltage on this card by about .05 volts for stability, and am using the current nvidia beta drivers.

For redundancy..now that's hardcore!!! lol
