Nvidia 570 SLI...

[zer]

Hi everyone. I'm thinking of adding another 570 GTX to my system(AMD Phenom 965BE, 6Gb RAM, Win 7 64bit). Two quick questions:

570SLI are equal to which single card? Say, 770?

What PSU do i need for 570SLI? I currently own a 750 HX COrsair.Is it enough?

Many thanks!

2x 570's are way more powerful than a 680/770 (same card basically).

Not sure if your CPU will bottleneck them though, what clock is at?

I haven't overclocked it, so it's 3.42GHz! Full CPU name is Phenom II X4 965BE.

So, SLI 570 is s/thing like 780?

Do you play at 1080p? If so, I would advise against it as you will be VRAM limited.

I had SLI 470's for a little while and the stuttering due to games running out VRAM was pretty bad.

No, not 1080p.My monitor is a Samsung 22'' T220, @ 1680*1050

Which games will you be playing? You will see little to no gain going sli depending on what you play.

You know, the usual suspects...Battlefield, Bioshock Infinite(still haven't finished it), Assassin's creed 4.....Plus whatever new comes...
Nocky24, i see we have the same PSU. Do you find it lacking?

Not sure on that RES but at lower RES its about the CPU more.

2 Points,

1) Pretty sure your CPU would bottleneck 570 SLI
2) You wont notice the difference much (if atall) on that low-a-res display.

No point, until you upgrade monitor & CPU, but then why not get new GPU(s) too.

I used to run MSI Twin frozr 570 sli (overclocked).

I have gone from those to a Gigabyte 780 ti OC windforce.

I can say from experience that the 780ti is about 25% faster than my old 570 sli setup (benched and games). I believe from the research I did at the time of upgrade that the GTX 780 is about 15% faster typically, and a 570 sli setup may be considered comparable in most games to a 770. depends of course what you run, resolution etc. but that is my honest experience.

it is never a straight comparison because it depends heavily on software support for SLI and what you are interested in playing.

I am about to SLI my 780 ti as at 1440p @ 90hz it can't cut it.

Personally single card every time though if possible.

A double 570 might not be cheaper in the long run, as you'll have to take into account the power consumption as well. TDP for 2x 570 will be around 440W (official specs) or 480W unofficial reviews, Vs. a single 670/770 will be just 170W official.

Also in PhysX games like batman it will fall short due to having way less cuda cores than even a 670. (SLI 570 960 vs single 670 1344, 770 1536.)
