Hello guys,

Can anyone give me a hand at all? It's my first attempt at going SLI and I would like to ensure all is compatible and a good choice.

Current setup:

Power Supply: Corsair TX650 V2 650W
Processor: Intel Core i5 3570K 3.4Ghz
RAM: 8GB Corsair Vengeance DDR3 1600Mhz/PC12800
Motherboard: Asus Sabertooth Z77
Graphics card: Palit GTX 670 2GB Jetstream

Now I can get my hands on 2 Asus GTX 670 2GB from a friend in exchange for my Palit GPU.

Could my current setup run the x2 Asus GPU's well, and are they OK cards?

I have an Asus 21.5 inch monitor running atm, and I also plan on adding another 8GB of ram.

Cheers.
 
That PSU will be enough but I am guessing at stock clocks and not leaving much for overclocking. I would prefer someone else to confirm though who has a similar system.
 
Thanks - I was lead to believe the PSU would be more than suitable, but I am not against an upgrade considering I will be upgrading my ram too. My CPU is also overclocked to 4.2GHz

It is all about the volts :) I used a 3930K and 2 x 680's on a 750W with no problems. It pulled around 800W at 1.34V - and a decent OC on the 680's (no extra volts) but that was at the wall with 3 monitors, so knock off the extra monitor power and extra voltage from the 3930K and you will be on the limit.
 
What res are you playing at? 1680? Also, what are you playing?

Are the cards Direct CU II efforts?

edit - just realised that you have exactly the same setup as me, save for the PSU and monitor. Not running a 650D per chance as well are you?

They are Direct CU II cards yes.

Corsair 600t case.

Resolution will be 1080p, mainly playing BF4, and DayZ.

Failing that I could actually get 2 Asus GTX 770's - if they would perform better than 670's?

2 770's would perform better than 2 670's without question, but I don't think there would be a massive difference in it, not enough to warrant the price difference.

Perhaps if you sell the games then 770's are a lot more viable.

There would be very little difference in price if I was to buy new, so price ins't a problem really.

May opt for that if my PSU would hold out, with the added ram. From research, everything else seems compatible for an SLI.

Is there anything I should know first, and does everything come in the box to SLI from the word go?
 
Similar then, very similar.

Yep, the 770s would outperform the 670s but not by a huge amount - especially at 1080p.

Although not sure how accurate some of those numbers are!

FWIW I'm currently debating another 670GTX to go with my current Direct CU II too, and I think I'll be more than happy with that setup for some time to come - certainly more so than splurging out on 770s.

The part needed for SLI comes with the mobo, so make sure you haven't lost it :D

Oh dear! I better get checking haha!

Can't check the site at work :(

Any idea what FPS I would likely average on BF4 with this revised setup? And in closing, would you agree the PSU is sufficient?

Cheers again.
 
I can get fps anywhere from as low as 50-180 in BF4, most of the time I'm above 100fps.
Some maps are better than others and on top of that they need to patch it plus AMD and Nvidia will be getting better drivers as time goes by.

This is on a 1080p monitor, when all is good in bf4 boy is it smooth :)
