Noob Updating GPU Set-Up: Please Advise

post #1 of 19
Thread Starter 
To preface, I'm somewhat of an idiot when it comes to computer hardware. Years ago I used to keep up on what was best and all that, but it's something I fell out of and now I really don't have much of an idea as to what I should be doing.

Basically, a few years ago I bought a pretty nice desktop from someone who was really into high-end hardware. He had a SLI set up with a 2 gb GTX 460 as a primary card, and a 512 mb 9800 GTX as a PHYS X card.

What I'm looking at getting is a 2 gb GTX 770 Windforce 3x card. http://www.newegg.com/Product/Product.aspx?Item=N82E16814125463

My first question is if it is possible to run the GTX 770 as the primary card, and the GTX 460 as a PHYS X card. Again, I'm an idiot when it comes to this, but using the PHYS X set up, the 770 won't be bottlenecked by the 460, correct? I've heard with SLI that the better card can be held back by the lesser card, but the set up in my desktop as is seems to indicate otherwise. If I can't run these cards together effectively, will the 770 on its own be significantly better than the 460/9800 combo I'm running now?

Finally, I've heard that the 770 has the option for a 6 pin or 8 pin connection to the power supply. Reviews I had read on the card said pretty much across the board that the 6 pin is not recommended. My current cards look like they have 6 pin connections to the PSU so my assumption is that that's what I have to use. Is it a huge issue if that's how I need it to be connected?

Sorry if any of that seemed confusing. It's a bit difficult to describe stuff that you yourself don't understand in full haha. Please advise! biggrin.gif

you cant run a 460 and a 770 in sli together.. the 2 cards need to be almost exactly the same, especially when it comes to the amount of memory and its type and bit rate.

you can run the 460 out of the sli loop.

and if the card has a 8 pin u need to use all the pins. you can (it will likely come with) buy an adapter to turn a 6 pin into an 8 pin.

and just because you haven't been following pc hardware for a while doesn't make u an idiot.. haha, it changes with the seasons.

Absolutely, but the only way to know if you'll benefit from dedicating the GTX 460 to PhysX is by trying it with and without. So, what you do is, you keep the card installed on your motherboard. Then, in the NVIDIA Control Panel, just switch between the 770 as the PhysX processor and the 460. Compare both and see what you think. If you get identical performance with both configurations, then sell the 460. Or, put it away in a closet as a backup. Or, build a backup PC with the 460 as its video card. hehe :)

This card has an 8-pin and a 6-pin. Both connectors must be used in order to power this card. Do not use one or the other; use both.

 

What is the make and model of your PSU? If you don't know, then please take a look because it's actually very important.

you can run the 460 out of the sli loop however, but I promise you wont need it with a 3x 770 sli setup hahaha.

 

He's not asking about putting them in SLI together; he's asking about dedicating the 460 to PhysX. I answered the question though, so don't worry about it. :)

nice arrogance, and yes he stated many times the words "SLI", but if all he is trying to do is dedicate one card to PhysX then he can do that without it being a sli setup.. was making sure he understood its not sli buddy.. but thank god u cleared it up..

twocables did raise a good point, make sure your psu is adequate for the card ur about to throw at it.

honestly logically you would think that 2 cards is better than one in this case, but the 770 is such a leap from the 460, im not sure if you would be improving performance dedicating the 460 to PhysX as the 770 has a much better everything, PhysX engine included.

No, I was just clarifying something that you were not clear on, and I was also stating a fact: I answered it. I was being honest, not arrogant. Don't project, because that ain't cool. Give the benefit of the doubt when you think the negative instead of the positive.

 

Anyway, just re-read his post again and I promise you that you will see that he is indeed talking about using the 460 for PhysX.

So it's actually a ThermalTake Toughpower 750W ATX 12V. I honestly thought that I had a lot more wattage than that to work with, so I think I'll need to upgrade my PSU. I can't imagine 750W is enough to run both cards plus the rest of the hardware.

Do you have any good recommendations that would be sufficient (and be compatible with the 770)?

Also, I never mentioned that my motherboard is an EVGA nforce 780i SLI. Pretty sure that is good to go.

No, that's major overkill for this. You're all set. Plus, it's a good quality-made PSU. Don't replace it.

Uh oh. So, then what CPU do you have?

 

You could be looking at bottlenecking the 770.

 

Oh, and let's settle the argument: were you asking about using the GTX 460 for PhysX, or were you asking about putting the 770 and the 460 in SLI together?

Oh, that'd be great if true. I figured with both the 770 and 460 plus other hardware, I'd be out of luck. But then am I back to having an issue with connecting the card with 8 and 6 pin?

I was asking about using the GTX 460 for PhysX. Sorry if that was not worded in the best fashion.
