Need some info from AMD users

post #1 of 9
Thread Starter 
Hi, I currently own a GTX 670 FTW, but as I plan on buying a 2560 x 1440 panel I'm looking to replace it with either a 7970 or 7950 for the extra VRAM. My question is: is it true that AMD GPUs are less 'smooth' than NVidia cards? Looking at benchmarks, I can see that AMD cards tend to peak higher in terms of fps, but also to drop to lower levels than their NVidia counterparts. As an AMD user, has this been your experience?

Do you plan of going single cards? If so, they are both as smooth. It's crossfire that is known to have slight issues until AMD fix it. It,s barely noticeable but it is still there..
They are suppose to have a fix before End of July.


But I don't think you will notice that much difference from a GTX 670 2GB to a HD 7950. If I were you, I would wait a little bit more for next generation of cards to release. Going from GTX 670 to HD 7950 is not an upgrade but a sidegrade.

Thanks for the info. Yes, I only plan on using a single card. I realise that it would be only a side grade to go from a 670 to a 7950, but the main reason was for the extra GB of VRAM. However, I'll most likely go with a 7970, especially if there's another price drop to combat the release of the GTX 700 series this month.

OP as you said it would be a sidegrade. the best value for money would be with HD 7950. at the same clocks HD 7950 is 5% slower than HD 7970. the average overclocks on HD 7950 boost are 1100 - 1150 mhz. at those speeds you match or slightly exceed HD 7970 Ghz perf. thumb.gif

the HIS HD 7950 iceq boost uses a 2.5 slot cooler. the card is 295 mm long and does not have vrm heatsinks. the msi hd 7950 twin frozr has vrm heatsinks and is a much more compact card at 262 mm. both cards have voltage control.

also the GTX 780 is launching on may 23rd. so i suggest you wait and see if thats affordable for you.

Thanks for those great suggestions, the only problem is I'll be watercooling the card, so I need a reference PCB rolleyes.gif I'm really looking forward to the 780, I was originally planning to sell my 670 and put the money towards one, except then I read a rumour that it's going to cost almost as much as the Titan, so I'm exploring other options : ( Either way, I'm going to wait until May 27th before I make a definite choice.

if you are watercooling HD 7950 go with a card which uses a reference HD 7970 PCB

http://www.pccasegear.com/index.php?main_page=product_info&cPath=193_1311&products_id=22948

the above card uses a reference HD 7970 PCB

http://www.overclock.net/t/1281711/hd7950-revised-with-reference-hd7970-pcb-club

the price of the GTX 780 is expected to be USD 550 - 600

Honestly, and I'm not a current AMD user (although I've been AMD in the past), you should just keep the GTX 670 and wait until either the GTX 700 series refresh in June, or the VI release in Q4. The only game that has ever come close to being limited by 2GB of VRAM has been Skyrim with about 16 mods, including texture and particle mods. I've honestly never been over it and I'm running a 1440p panel (main gaming monitor), along with a side 1080p.

Save your money and stick with what you have. Upgrade later on. You won't notice much if any vram limitations at all in gaming on a single 1440p. Wait till June or Q4 to decide what you want. 2GB is absolutely more than enough right now.

I did that same sidegrade in December. I figured a 7970 was going to be tons faster than a 670 FTW according to some here on OCN. It is indeed faster but not by enough to ever justify changing cards. That being said, it was a nice change to have another AMD card under the hood. AMD is currently getting their ducks in a row dealing with GCN and they are making progress and their drivers are the best they've ever been.

I'd hold onto the 670 and wait to see what becomes of the 700 series. In fact, the 670 is good enough to hold onto until we see what the true next generation is going to bring at the end of the year.

Agreed, it's only worth upgrading VRAM to 3GB if you're using multimonitor and multi-GPU (Which you'd better be tongue.gif)
