Surround with 2x GTX560s good or no?

post #1 of 6
Thread Starter 
I was going to buy 2x gtx560s to mess around with surround but I'm wondering if it'd even be worth it with 560s and not 580s or higher. And, if I do get two 560s, what kinda power supply should I get? I figured this 520w wouldn't have enough power for it anymore and suspect that's probably why my current 260 will shut off and on for a split second for no reason.

A GTX560 costs about US$170 and so two will cost around $340. Your PSU might (or might not) be able to handle that according to the review below. However, it does not have enough native PCIE power connectors and you will have to use molex adapters.

IMHO, a better alternative is to grab a single GTX670. Its typical cost is about US$399. And the Gigabyte GTX670 OC Windforce appears to be a good choice (which is currently out of stock at Newegg). One single card will drive three 1080p monitors very decently. As such, you have less heat, less power consumption, no potential SLI issue. A GTX670 is more powerful than GTX560Ti SLI. So, you will have much better performance too.

(Your HX520 should have enough juice for a GTX260, assuming it is not malfunctioning.)

A single 670 is a nice choice. I'm trying to spend as least as I can so it may be the cheapest option. I was also going to pick up 3x Asus 23" 1080p monitors for whichever I go to as well. I'll keep an eye on the 670 and see if I can grab one.

But my 520w psu should be enough power with 5 hard drives and 2 ssd's then and a h70 heatsink?

and 1 gtx670 is only about $800, I think I'll just go this route then. Assuming I don't need another power supply to power it.

Only question now is will a gtx670 fit in a HAF 912 case.

A GTX670 has a typical length of 9.5-10'' while your HAF912 can accommodate a card of length up to 10.6'' without removing the HDD cage. As the Gigabyte Windforce OC is 11'', you will have to pick another one. Not a big problem at all.

Your HX520 should be able to handle a GTX670 plus the 5 HDDs and 2 SSDs and a H70.

(BTW, GTX560 SLI is not a good idea for 3x1080 because the 1GB VRAM per GPU will occasionally form a bottleneck, thus requiring you to lower game settings.)

So if I removed the HDD cage the windforce would fit just fine? May have an excuse to throw the hard drives in a backup system for a server only system then.

Yes. If you remove the HDD cage, you will have ample space (15.4'') to take in any card, including the Gigabyte GTX670 OC Windforce.
