GTX 460 single and sli is there big diff?

post #1 of 10
Thread Starter 
I'm looking to sli gtx 460 but I want to know if this is worth it? Are there considerable performance difference between single and dual setup?

You should see fairly close to double your FPS in many games, SLI works pretty well these days.

It will also allow you to max out more settings for eye candy. ;-)

Awesome jump in performance. High 90%'s scaling.

No doubt of substantial performance boost coming from a 2nd card.

However, an upgrade of monitor is probably equal worthy of your consideration of your money spending. Your current LG Flatron 19" (native 1440x900) should not give much trouble to a single OC'ed GTX460 1GB and so adding a 2nd card is not critical, IMHO.

To this regard, increasing the monitor size to, say, 24'' (1920x1080) will likely to give a higher visual satisfaction and immersion factor (vs higher fps coming from SLI).

I see. So the monitor supported resolution is another factor. If I hadn't known that, I'd probably have installed and SLI and not notice any big difference. I guess I'll look into some monitors as well. One more question though, would my PSU support SLI with ease or just barely?

You should be ok. I would say the answer is "neither"
You can sli 460s and be ok for sure (the joys of gf104), but I wouldn't say you can do it "with ease". That's pretty much the limit for a 650 watter. I wouldn't recommend sliing 470s for instance.

Edit: A good match for that 460 would be a pretty new 24-26 inch 1920x1200 display. You should be able to find one for around 300.

460's dont use much power.

2x GTX 460's @150W each = 300W
Power= Voltage x Current
Current= 300 / 12= 25A

Meaning you just need to be able to support 25A on your 12V+ Rail

Cards don't really add up like that for power consumption, two cards != the max consumption of both cards.

That said you will see about a 80% gain in performance and about as much increase in power consumption, well worth it.
