SLI question GTX760

post #1 of 12
Thread Starter 
I have a GTX760 and i5 2500k@4.5Ghz, plan to add a second graphics card. Since I had a Corsair TX650W v2 is it enough to upgrade? My motherboard (P8Z68 pro/gen3) just makes x8/x8 sli. Will I lose performance by this? And I will also lose performance by only have PCI-E 2.0?

Thanks

And worth doing sli instead of buying a better single GPU? I ask because a lot of people complaining of problems with sli and games that do not support.

it all depends on your personality - for me i have 2x 590s - and sometimes.... it can be a reallll PAIN IN THE BUTT -_-

for instance just recently my computer crash... why it crashed? wasn't sure til i spent a couple hours looking around. at first i thought my bridge died, then 1 of my cards. but eventually it was just the driver... or could it be my PSU crapping out on me? :O in most cases having 1 single powerful GPU is worth it cause it takes less work to figure out issues but again it is all your preference

I have never had a problem with a game "not supporting" SLI. I don't know how that's technically possible since it's handled by the drivers anyway... but that's a story for another day.

My SLI experience has been great and I'll continue to do it as long as I can.

2 760s in SLI will give you a great price/performance ratio. I think its tottally worth it since you already have 1 760. Normally i would recommend just getting the highest card you can afford and single card it but since u already have 1 760, might as well pick up another one for the massive performance boost.

kbyte IMHO i think you should just wait it out and just wait for the 800 series to come out later this year (probably in 3rd/4th quarter again) they will probably make the current 780s the new 870s and etc - with better cooling, power consumption

I would only go SLI/XFIRE if under these conditions

1) bought the cards at the same time
2) bought a 2nd card at a lower price by $50-$75 thats just my thoughts

I just do not play only AAA games. That's why I ask because I never had sli and do not know how is the experience of having 2 graphics cards.

But supposedly will have more consumption / temperatures than a single GTX780 but much more raw power.

Well first off, what resolution do you game on?

It really depends on the person. It almost sounds like you would be happier with a single powerful card over troubleshooting sli issues that can occur. Kepler and up seem to have been much better than fermi (5xx series) with sli and has tempted me to try sli again (last time was 560ti sli). The way I personally look at it is if a single card can deliver the performance I need, I stick to one card. Since I am on 1080p I dont have much of a reason to get more than a gtx770 (the bencher in me wants more though lol) I will say though, when a game properly supports sli its great, when it doesnt, its frustrating.

So honestly if your still on 1080p, a gtx 780 will be a good "overkill" card, but even a gtx770 will offer great 1080p performance.
