GTX 560 SLI Power?

post #1 of 19
Thread Starter 
I have 300 euro to spend on graphics card/s and was thinking about getting 2 GTX 560's in SLI. I have a few questions about it first.

1: Is my 620W Power Supply enough to support them? (Corsair HX620)

2: How is SLI in games now, does it have good support? Is Microstuttering still an issue?

3: Am I better off going for a single GTX 570 (same price)

I've just sold my GTX 260 and am now running solely off my iGPU on my i7 2600k. It's pretty awesome considering, but I'd like to get this new upgrade ASAP, so I came to the wonderful overclock.net forums for help

Thanks in advance guys!

First of all, if you're considering to SLI two 560's then a 570 would be more worth it. If you plan to SLI two 560Ti then you have a few options here. The Ti's are a considerable step above regular 560's.

1. HX620 is a very solid PSU and will definitely be enough for SLi 560ti. Will be no problem at all.
If you plan to SLI anything above that (570, 580, etc) then a 620w won't be enough.

2. Very dependent on the game and driver support, but for the most part this is not something you need to worry about in today's games.

3. 560ti-> SLI can outperform a single 580. But you lose out on some upgrade potential.

My advice: Go with a single 560ti for now. SLI two 560ti's if you don't feel like its enough power. If you want to go with a single card, then save some money and go with a single 580.

yes, but looking at the statistics, the SLI performance increase between GTX 560Ti and GTX 560 is minimal at best, 5% or so. When, looking at the price, I can get a GTX 560 SLI for just under 320 euro and GTX 560Ti SLI for 400 euro.

The main fact for me is, I've never SLI'd before. I don't know what I'm getting myself into, but I do know my numbers and I've done a lot of research. From benchmarks, the GTX 560 SLI > GTX 560ti SLI for me, bang for buck.

I'm pretty sure the ti outperforms the standard 560 by more than 5%...

I'm talking SLI performance. I didn't look up the reason for it, but I was as surprised as you.

My thoughts are same like you,
go with gtx560 sli(better value than 'ti' version) & your psu will nicely power them.

The 560 Ti is about 10% faster than the 560 non-Ti but when you're in SLi this difference decreases because, in general, the more cores the lower the scaling.

Not only that, but the 560s in SLi have a ton of processing power for any situation where 1GB of VRAM is used. Yes, the Tis are faster in SLi but they are still limited by the 1GB of VRAM so you can't really take advantage of the extra processing power, especially with a 60hz monitor.

Thanks for explaining it, I could see the difference was only small from the benchmarks, but I didn't know why.
