Video card question

[Prophet171]

Ok so which is better performance,?? two GTX 770's sli'd OR one GTX780ti? Need pros and cons to both of these options please. Help me out

 

[esco_sid]

always go with the most expensive single card configuration you can as single GPU will have least issues in games and then you always have the option to get a 2nd one down the line when prices drop. but wait for gtx 980 thats what i would do their coming out soon.

I found this thread. It should get you started with some ideas.

Two gtx770's will perform better than one gtx780ti. http://www.guru3d.com/articles_pages/geforce_gtx_770_sli_review,19.html

A 780ti will need a 620W power supply. 2 x gtx770s will need an 850W power supply

a 780ti costs about $600. 2 x 770s will cost $600

You can then add another 780ti later.

SO best bang for your buck type deal would be go with the two SLI cards because would perform better right?

 

[i7Baby]

Not if you take the cost of a power supply into consideration.

 

[Prophet171]

I was going to get a 1000W PSU, i should of mentioned that so that isnt a concern.

I'm with esco - wait for the 980. i7 Baby - have you ever done SLI?
When it works(after you overcome hurdles - heat, drivers, game support, power supply requirements), it works well. I have done it in the past with SLI GTX 460s - not in a hurry to get another GTX 670 to SLI in my work/gaming computer.

So its a big hassle to SLI? what you mean by heat drivers and game support??

 

[maxtex]

heat = heat (2 cards generate more heat than 1)
drivers = drivers (can take a while till the drivers get optimized for SLI configurations, like when new games come out)
game support means not all games are optimized to utilize SLI, although pretty much all of the big, demanding titles are these days.

SLI is just more complicated than a single card, one card can render a frame more smoothly than 2 cards working simultaneously so I'd imagine (tho I have no experience with SLI myself) you can more frequently experience a "lagging" feel to the motion on the screen.

 

[Prophet171]

ahh ok, so 'lagging' feel for SLI? and what do you suggest you do for the heat if its a problem?

 

[i7Baby]

I have 2 x gtx670s now. I have no problems.

 

[Prophet171]

ok perfect so shouldnt be a problem.

 

[Prophet171]

how much of a pain is the drivers/game support?

 

[i7Baby]

Most games now support SLI. http://www.geforce.com/games-applications/technology/sli

Some still have problems to be fixed eg Watch Dogs

I know COD Ghost was a very crappy game, but it did not support SLI for months.

[Prophet171]

really eh cod ghosts didnt support SLI, weird for a big title like that.
