660 Ti vs HD 7870

[jssaylor2007]

I received an HD7870 and a 660Ti for Christmas this year for a computer build i am doing. Which should i exchange for the other and why.

I am going to be running dual 23" 1080p monitors, and I plan on trading one of the cards for the other to run in SLI or Xfire.

Your opinions would be greatly appreciated.

Thanks,

In advance, I know this question has been asked to death, but I have searched up and down, and cannot find anything relating to these two cards compared in SLI/Xfire.

Some various info on my build.

Power Supply: Corsair AX750
Mobo: ASUS Sabretooth z77
CPU: 3570k
Ram: GSkill Sniper 4GBx4 Ram


That should be all relevant components.

I mainly use my PC for gaming. Nothing Huge on the gaming, but I like to keep my builds somewhat future proof in cas something worthwhile comes out.

My most taxing games would probably be Skyrim with lots of mods, and FarCry 3.

Ive used that, but am looking for more of a "from my experience" type of post.

Also the Anandtech benchmarker doesnt do SLI/XFire as far as I can tell.

My SLi'd 660Ti's are running well and have given me no problems so sell the 7870 and get another 660Ti, hows that for a "from my experience" post? :lol:

Ok here I go:

660 Ti is £200-£250.
7870 is £150-£200.

660 Ti is faster, but 7870 gives you more bang for the buck. If you do intend to O/C the 7870, however, it will definitely outpace the 660 Ti. The GTX 660 Ti should be compared with the 7950 not the 7870. 660 Ti is just too powerful for the 7870...

Yeah, that's what I'll do... Actually sell both cards and get a GTX 670.

 

[jssaylor2007]

So does noone have a comparison between these two cards in SLI/XFire?

I'm liking the GTX670 idea. I wouldn't worry too much about SLI vs Crossfire, since both GeForces and Radeons tend to achieve the same kind of gain from a second GPU (average of 80% gain, but varies hugely depending on the game). This may help:

http://www.techreport.com/review/23981/radeon-hd-7950-vs-geforce-gtx-660-ti-revisited

Shows the GTX660 Ti delivering far superior results to the Radeon above the model you're considering. It's definitely a far superior card.

Gtx 660 ti is meant to challenge the 7950

7870 X-Fire may cause stuttering. That will be really annoying.
Get GTX 660 Ti SLI.
Or get a GTX 670 and SLI it later.

Sell both, get 670 FTW edition.....why....because in my experience SLI/Xfire doesn't ALWAYS work perfectly on every game....in some games...it even slows the game down...true. In Darksiders 2, the game ran horribly in Xfire 6870 x2 cards. Where as FarCry 3 looked WAY better using Xfire....literally 50% increase....it's just not worth the extra HEAT the power supply was cranking out so I chose to sell 1 of the 6870's and am planning on getting the 660 ti after I sell my other 6870 AMD gaming bundle and the new 7850 I'm getting. OR... I'm going to keep the 7850, sell the other 6870, then wait until Nvidia's newest GPU and get the starting ground one. Not quite sure yet.... I may just keep the 7850 for awhile.

 

[Soul_analyzer]

a better idea is changing both for a 680

 

[iam2thecrowe]

i agree with changing both for a single faster card, avoiding the problems associated with a dual card solution (particularly crossfire). If you want to go the dual card route, i would chose 2 x 660ti's all day every day. Nvidia's dual card sli solution is superior in every way to amd's crossfire, less stuttering, lower frame latency and better game support.

"As we expected, both from The Tech Report's background with this and Nvidia's in-house examples, we see that AMD's Radeon HD 7870s in CrossFire tend to suffer more dropped and runt frames than a pair of GeForce GTX 660 Tis in SLI. This addresses much of the trepidation about multi-card configurations expressed in Best Graphics Cards for the Money, confirming that two of Nvidia's boards appear more appealing. AMD even admits it's playing catch-up in this area, and is addressing its shortcomings through successive driver improvements."

every site who has tested frame latencies etc on cards with this new method has found the same result with AMD's cards dropping frames, stuttering etc.
