I have a faulty GTX 660. I tried everything from updating the drivers. The mobo, processor and all the other components are fine. The GTX 660 used to play Arkham City on very high at 1080p on a constant 60fps. I can't even get that anymore. Harley Quinn's revenge I was getting 4 second freezes. Even deleted the Bmengine in the WB Games folder. I got this video card in 2012. So I want something more powerful in 2014.

GTX 660 superclocked 2GB SLI ready GDDR5(EVGA)
i5 3570k not overclocked
16 GB RAM DDR3(I think possibly I need to move the RAM in the blue slot to fix the fps, I'm most likely wrong)
2 TB 7200 RPM Windows 7 WD
1 TB 7200 RPM Ubuntu 13.10 seagate
Asus P8z77 v LX( want to upgrade to the LK for SLI in late 2014.
Cooler Master heatink hyper 212+
600w PSU(current)
LG blu ray drive
Realtek HD sound and wifi adapter(impossible to have ethernet in my situation


I want to either SLI two GTX 780s or get a 780ti or at minimum settle for 2 GTX 770s. What are my options? Because my PC is ok for gaming, it's great but not awesome.

How is the RAM configured? If you have four slots and two sticks then it should be: stick, empty slot, stick, empty slot.

You're going to need a much heftier (talking 850w and up) PSU to run dual 780's or 780 Ti's.

You're wrong on the RAM... it's the Graphics card holding you back! Maybe add another for SLI or replace your faulty one with a 760?
PSU: for what you have now is fine. For 2-way SLI a 750w psu would be fine but an 850w would be better espically if you want to overclock.

try rolling your gpu drivers back to a pre-314.22 whql driver. I would also try to overclock your cpu a little.

as for what you're talking about, understand that a 770 is about all you need at 1080p. unless you plan to get a higher res monitor or more monitors you don't need more then just one 770.

If you still want to spend more then that on a gpu, a single 780 would be more then enough at most resolutions and monitor orientations.

btw: your current pc is already better then a ps4

I find very few situations (and I say that just to avoid a definitive "never") where two cards in SLI are better than one of a higher quality card outside of budgetary reasons. If nothing else, you're consuming more power AND making two points of future failure for a component instead of one. If you can afford a better card and one is available, go with the better card.

Well RAM can influence how I play the game. I know the GPU is obviously the most taxed item when it comes to gaming. But maybe I can just stay with a single 780 and go up to 750w

Maybe that was true about multi-GPU configurations a few years ago, but now almost every single game that comes out has multi-GPU support from both nVidia and AMD--my dual 270X's are faster than a 780 or 290X at a fraction of the cost and they don't suck too much power at all.

Ingtar is right though, you don't need more than a 770 for 1080p. Anything else is overkill.

Well what about overclocking in the future. Isn't having slack power a good thing so the PSU doesn't die out faster?

Agreed that he needs a heftier PSU, but he would not need to go above 850W. I ran the hell out of my overclocked 780s in SLI and only peaked out at 575Watts for total system usage (and that was a mere 1-2 second blip). The average was more along the lines of 450Watts. All while using an AX760i and an overclocked 4770K at 4.3GHz.

Yeah I was thinking more along the lines of Ti's and if he wanted to overclock...power usage skyrockets at that point and the less his PSU has to work to supply power the less heat it gives off, so goes the old adage "bigger is better" :p

You are fine running a single 780 on your current psu.

Of course I know you're right. But I am talking about just in case I want to go further. But to be realistic I am in college. But I want something awesome to game on after working.

an overclocked 780 and i5 might brush close to 550W... understand the most "efficient" and ideal range for a psu is a system that hovers around 2/3 of the rated psu strength, your system with a 780 will hover around 350W of usage, which is pretty close to "ideal"

Ok, so what about a single 780ti on my non SLI mobo with the current 600w?

Here is a bit of an action plan for you:
1) Get 780Ti
2) Get Corsair AX860i or equivalent Platinum Plus PSU (will give you plenty of head room for an overclocked 780TI SLI in the future).
3) Game it up for a while (a few months or so)
4) Get another 780Ti for SLI and get ridiculous frame rates at maxed out graphics settings.
5) Overclock your CPU a bit (if you have an appropriate cooler on it).

I wouldnt even think about getting SLI 780 Ti unless you get a 1440/1600p monitor, otherwise its just wasted performance.

Power requirements:

GTX 780 -- 222W (DC) each
http://www.techpowerup.com/reviews/Palit/GeForce_GTX_78...
Base System: i5 3570K -- 83W(DC) [109W (AC) @ 80% AC->DC conversion efficiency]
http://www.xbitlabs.com/articles/cpu/display/core-i7-37...

So... that's
527W (DC) power or 44amps on the +12V rail

* Make sure you have maybe over 550W (or 46amps) on the +12v rail as most of this power will come from from the +12V rail. Focus on the +12v rail (as this is important); 600W/50amps might be a little safer.
* Make sure you have 4 dedicated/proper 8-pin PCI-E power connectors; you want real ones from your power supply and not use converter cables.

Check your CPU/GPU heatsink and fan. I had a problem where I was getting terrible performance. The cause turned out to be that the heatsink had way too much dust in it, and one of the wires from the fan had somehow got caught in the fan and stopped it from spinning. The CPU was throttling itself to protect itself thermally, and thus the performance was terrible.

I don't think your rig has a hardware issue and you should be getting good performance out of that game. I would suspect either some kind of heat issue, or a software/driver issue.

Also, as to the ram, just make sure if it's two sticks it's in matching color slots.

Totally missed the part about the failing GPU. I agree with TriBeard... try to see if you can fix your video card first instead of wasting money on a new card that is only 1 generation newer.
* Try cleaning all the dust and make sure the fan is still spinning at full speed like when it was new (like TriBeard suggested)
* Check the warranty length. Is it a model with 1 year or one of those models with several years warranty?
* Also, you can try lowering the clock speed, GDDR RAM speed, etc... by a little bit to see if that is enough to keep it stable.
* As a last resort, you can try removing the heatsink, reapplying thermal compound and putting the heatsink back on.

As you said, the card used to run very well; your problems sound hardware related (possibly even easy to fix)... and if you can fix it, you will have just as fast a card as you had before (unless the only solution is to lower the clock speed a little). So, there's really no need to get a new card if you can just solve the hardware issue.

On a related note, if you must get a new card, consider what the_crippler said. Benchmarks show that two cards will not perform quite as well as a single fast card. If you can just get 1 fast card, with equivalent performance, that would be better.
