Want to pull the trigger on a GTX 580 but have questions

Last response: in Graphics & Displays
Share

my current power supply is only 750W

I'm running:

i72600K stock

GTX 560TI

Hyper212 CPU Cooler

Asus Sabertooth P67 MOBO

8GB Corsair Vengeance RAM

1XDVD ROM

and my PSU I think will likely be the issue

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

that is my current psu


I'm not the best with this stuff. Anyone have an idea of how much power I'm already using with the current setup? Will I need to upgrade the PSU for the 580?

580's i'm considering

or

one of those two, and I will likely SLI them before years end. Which one I go with I'm not entirely sure yet, but I KNOW FOR A FACT I'll need to upgrade the PSU when I SLI the 580. Any suggestions on a PSU for the SLI on two 580's along with everything else in my setup would be greatly appreciated.


But for this moment, the only thing I need to know for certain is if my PSU will be fine for one of those 580's RIGHT NOW

You already have a 560Ti so why go for a 580? you could go for the SLI option with 2 560Ti which can easily beat a single 580. You could also wait for the 600 series that is rumored to be released next year. Is the current 560Ti not enough for your gaming preferences now?

eh...the 560TI isn't the greatest with a lot of games at 1080p

struggles to hold 30-40FPS in a lot of cases

I think he means get a another GTX560 Ti and SLI with your existing GTX560 Ti.

This would be the least expensive but more powerful option as GTX560 Ti SLI will outperform a single GTX580.

Exactly as hunuok says. You can save more money on another 560Ti now and have extra cash on hand in case the 600 series is launched next year. If you are not satisfied with the SLI set up, GTX 560Ti are easy to sell so I think you wont have any problem.

I have a 560TI myself and mine does 40fps in every game on high - max settings on 1080p :??:  Even on BF3

Would see no reason to upgrade, just wait till the 600 series. I'm gonna buy the 680 (or whatever it is going to be called) myself then, but don't really so the point in upgrading to go higher then a 560 when on 1080p. (maybe on 2560 it would be usefull)

the power supply is fine. you guys with your sli. you have absolutely no clue how much better the 580 will be over the sli 560's. there's more to gaming needs than the benchmark charts show you. FPS isn't everything.

The power connectors will be on the end of the card facing the side of the case on the 580s. All of the PCI-E power cables on your PSU are 6+2pin. So you'll just plug in one of them with the 2 extra pins hanging out and the other one with all 8. The difference is that the 6-pin can supply ~6A (~75w) at 12V and the 8-pin can do ~12A (~150w) at 12v.

just how much better is the 580 in comparison to my 560TI?

Really looking to get opinions from those who have seen and experienced both for themselves. I'm just wondering on average how many more frames you would get in a game like New Vegas with a few demanding mods running. Just Cause 2 with most settings on High 1080p etc etc

things like that

edit

can the 580 run GTAIV at 1080p 60FPS at high settings?
