Upgrade, SLI, or wait?

Adam Ferrick · Oct 27, 2013

Hey everybody, with the release of AMD's R series cards, the next generation of games coming out soon, and Nvidia's next cards coming sometime soon I've thought myself into a predicament.
Here are my current specs:
CPU: Intel Core i5-3570K 3.4GHz Quad-Core Processor ($209.98 @ Outlet PC)
Motherboard: ASRock Z77 Extreme4 ATX LGA1155 Motherboard ($124.98 @ Outlet PC)
Memory: Corsair XMS 8GB (1 x 8GB) DDR3-1600 Memory ($67.99 @ Newegg)
Video Card: EVGA GeForce GTX 670 2GB Video Card
Power Supply: XFX 650W 80 PLUS Bronze Certified ATX12V / EPS12V Power Supply ($59.99 @ NCIX US)

Unfortunately, it looks as if my GTX 670 FTW Signature 2 has been discontinued

Sad day.
So my options now are SLI with a different brand or try to sell my card at some point and buy a better card (770, 780Ti, R9 290X).
So what should I do? And if SLI, is my PSU powerful enough?
Suggestions are welcome

PSU to small for SLI but good for a better single card. That would be my reasoning.

i'd get a 2nd 670 to SLi.

rolli59 :

nope, 650W should be enough power for SLi 670's and an i5-3750k

even overclocked.

750watts recommended and 4 x PCIe power connectors http://www.realhardtechx.com/index_archivos/Page362.htm Actual power consumption though is going to be under 600watts (or less than the 680SLI here) http://anandtech.com/show/6774/nvidias-geforce-gtx-titan-part-2-titans-performance-unveiled/15

gpu manufacturers always suggest bigger then you need. That's because they don't know what your rig is and what you're doing with it... also there are a lot of junk psus out there that don't give their rated speeds. so they tend to suggest much more power then you need.

Being as the 670 are 170w cards and I've had 170w 560Ti's in SLi on a 620w PSU I'd have to side with ingtar33 and say the OP is likely to be OK.

@OP, the cards don't have to be identical so any 670 will do.

Mousemonkey :

Both of those things are good to hear, my PSU being enough and having the ability to SLI.
I've seen benchmarks where the 760SLI has been close to or beaten the Titan in some instances, so I'm assuming the 670SLI would be similar. Would this be the best option over selling my current and buying a better, single card?

Mousemonkey · Oct 27, 2013

I would say so but then I do run SLi'd 660Ti's so I'm somewhat biased.

Adam Ferrick · Oct 27, 2013

In your personal experience or opinion, does it look like you'll have you upgrade to a better setup any time soon? Or are your cards good enough to last a few more generations of upgrades?

Adam Ferrick :

well, the way i look at it, a 670 is already close to a top end gpu. in 1080p there is little need for more power out there. Its definately an elite gpu... and scaling up to a Titan/780 or r9-290x would only net you another 20-25% improvement in gpu rendering power.

So the most cost effective solution would be to SLi your 670's... that should give you close to a 690 in rendering power. at $300 cost. you won't get that type of deal from any single gpu out there. So this makes the most sense from a cost/performance standpoint.

obviously a single gpu would give you a better more bug free experience. but it won't be as strong as the 670 in SLi, and it will cost more.

Thank you, sir, very informative and helpful. You are a gentleman and a scholar
