Whats your opinion? 7950 CF or 780?

post #1 of 21
Thread Starter 
Need some help before I make this decision. After going SLI with non reference coolers and not liking the heat in my case (even with good airflow), I figured I would go to a setup that would exhaust heat out of the case. I also want to keep something that is atleast 3gb as my modded skyrim gets up there routinely and sometimes over.

7950 Cf
  • So I was thinking about cf 7970 but after consistently reading how close the gap is for the 7950 to it Im thinking about these in CF http://www.newegg.com/Product/Product.aspx?Item=N82E16814161420
  • $580 for two of those. Based on the limited reviews Ive seen it is surpisingly quiter for blower style and draws in air from all directions around the fan. Which sounds good for SLI but Ive only seen 1 SLI review for this particular cooler.
  • All the microstutter talk about CF that isnt fixed yet has be nervous about the 7950's though, as it would bother me into not wating them anymore should I notice that. I want a smooth performance nnow. I cant be waiting for drivers to fix an issue that shouldnt exist (if it does actually exist tongue.gif )


780
  • I am also considering a 780, for the performance that is very close to Titan at $650 - could always SLI down the line should games demand it.
  • Wondering if buying the best single card you can afford should apply here?


I game at 2560x1440 - preferably at or around 60 fps. Overclockability is not a dealbreaker for me. But noise and temps could be.

the 670's I bought were close to $1k together before rebate so I definitely want to stay under that for the initial cost.

Thoughts?

7950s will be just as hot, if not hotter. If you're concerned about temps I'd go with a single 780.

Thanks for the reply

almost contemplating getting both options and testing against each other. Send back the loser

You just can't beat the four free games that come with it. I know most won't recommend Xfire because of scaling issues, etc., but AMD Catalyst drivers have been stepping their game up since 2013 started and it'll only get better. If you plan to get a second GTX 780 once you have the money in the future, then I would definitely recommend that if you have the money, or wait until the next generation of AMD graphics cards. In terms of raw performance, AMD usually wins the battle (I know the Titan is the best single GPU graphics card as of now, but AMD hasn't released anything to compete with it yet), but Nvidia has many useful proprietary features such as CUDA and PhysX. It's actually possible to use PhysX on AMD, it will just have to be calculated and dependent on the CPU. Also CUDA cores and stream processors are virtually the same, but CUDA cores perform better in certain CUDA core utilizing programs. In terms of performance and value, I would go with Xfire 7950s. In terms of features, expandability, and age, I'd go with the single 780. But if you have patience, go wait for the next generation of AMD GPUs, by then you will have more choices, and hopefully, lower prices for the 7950s and the GTX 780.

Thanks for that! Right along with what I was thinking as well.

I cant wait for next gen. These 670's are going back because for the price I paid I figured I could get something better and/or cheaper. So without those all I have is my 660 that is currently up for sale and that struggles with the games I play at my resolution. So I need something capable now.

Hmmm, decisions. Do I bank on AMD stepping up the CF support in a couple months or game on a single 780 uuntil I can afford a second ( for double the price of the 7950;s) . I'm kin dof leaning on the 7950's but I'm not sure. When tomorrow comes I there are 780's in stock and they arent over 600-650 I'm sure it will make my decision even harder. the more I think the more I feel like I should just grab both on the credit card, test the, , send the loser back and pay off the one I keep. I guess that would be the only way to know for sure

from what i hear the 780's will drop in at around the $600 mark. if you can do both and write up a comparioson on your findings that would be great for many users as well thumb.gif

Shoot if the 780 does come in at $600 even I'll likely grab two and call it a day. If $650 I might be able to grab one and the 7950's and do a little writeup before sending back - cause it was very hard to find 7950 x 2 CF vs Titan comparisons. Only 7970

For me this is kind of like the Chevy vs. Ford argument. I won't lie - I'm an nVidia fan. I had loads of trouble a few years ago with ATI drivers and trying to get a couple of ATI cards to work. They kept BSOD'ing. I switched to a GTX 570 and it has been smooooth sailing ever since. All of my rigs have nVdia GPU's in them: EVGA GTX 570, GTX 550ti, GTS 450 and I used to have an old warhorse 8800GTS.
Get the 780.

Oh, btw, Ford = First On Race Day

If you just plan to game at 1440p at around 60fps, you should be fine with Xfire 7950s. I guess it really depends on what games you plan to play in the future and at what settings. Remember, just because it is under 60fps doesn't mean it is unplayable. Also remember that with SLI GTX 780s, you're paying at least twice as much (assuming each card goes around $600-700USD) for a 10-20% performance improvement (I don't know exactly how much of an improvement it might be, but it probably is no where near a 100% performance improvement that you are paying for.)

Get a single HD 7950 now. get the second one after the frame pacing driver arrives in July. if you want more performance now go for GTX 780.
