has anyone switched from a 670 to a 7970? differences? better, worse??

post #1 of 68
Thread Starter 
Hi, i started a different thread and it was suggested i get opinions here, im unhappy with my 670 with stuttering issues, just wondering if anyone else has made the switch and whether it was a good choice. For the record i am totally ambivalent when it comes to amd or nvidia, i couldn't care less i just want the best product performance wise, and the 670 has been nothing but a drama really since the new drivers anyway. thanks.

I just did that last month.

When doing benches with Heaven and 3dmark11, the 7970 ghz at my max oc 1250 mhz would get me a couple frames more than my 670 FTW at max oc 1325 mhz.

Of course then we have the 12.11 never settle drivers which we've been getting beta's of since October. Provides good gains over the 670 in a lot of games.

However, that is not set in stone until we get a driver set that has the increases without microstutter. AMD has admitted to the frame latency issues and is looking into it so it may be awhile before we see a good result.

Quite honestly, at this point, I'd be waiting to see what the next generation will bring. The 7970 was more of a sidegrade than an upgrade. But I enjoy tinkering with new things so for me, it was worth it.

haha, yeah if im bein honest i also like to tinker lol biggrin.gif , but the stuttering is really pissing me off, did you have the same issues with the 670 that i am, and is the micro stutter from the 7970 a different thing to what im talking about? thanks.

No, performance with the 670 was fine. But I always did a manual clean uninstall of drivers as well.

The microstutter with the 7970 is minimal but noticable to me. It's almost like you skip a frame every now and again. I can see it in Heaven, Metro 2033, Skyrim, Mafia II etc.

AMD seems to think it happens because of memory. I'd tend to agree.

op, i saw your other thread in another forum. it could be your cpu. i play bf3 MP and at 64 man server with my cpu (i7) at 4.5 GHZ HT off (equal to an i5) my minimum goes down to the 50s. this is at ultra, 4msaa.1080P, and gpu at stock..

i'd imagine if i have my cpu at stock ht off it will go down to the 40s. i have not tried. now, with ht on, my minimum at 4.5 is at 60s and goes down to the 50s if i put the chip at stock.

hope i did not confuse you but anyway, i have no microsttutter of any kind i can perceive of except when playing metro where i have to oc the gpu as well to get rid of it.

with these gpus . . . you got to have that 60 minimum even if it is just 1080. 2cents.gif

yeah, thats what i have noticed, its not like im dropping to 40 or even 45fps, its like 55- 59 and it stutters, its so crap, i have it max'd aswell.

you can't rule out driver issue just yet. lowering settings do not make sense cause that 670 will be a waste. oc'ing is not an option either. idk, man. i saw your 3DMark scores and the gpu behaved normal. going to 7970 will definitely not going to fix it.

cheers man, well if its a driver issue then swapping would fix it tho lol, but yeah, i know what your saying, sit tight. With those cpu scores is it likely to be a bottleneck?

well, since you are in the amd section and if your current board is not meant for oc'ing - you might consider the vishera. cheaper and just as powerful as the i5 ivy. ha!. i am going to be flamed. you have the info to make a decision. gl!
