Do I need a 6870? - Page 2

post #11 of 52
Agreed, I personally would recommend going at least 8x/8x if you can. If you look at the table, you can see that there is only a big difference in the synthetic benchmarks, in the games there is only about a 3 FPS difference, which is not going to be noticable. With crysis, there was only a .2FPS difference, different tests tell different stories.

Bottom line: if you already have a x4 lane, you wont lose that much performance, but if you have the choice get at least 8x/8x for a dual card setup.

So as both of the links regarding x16/x4 vs x8/x8 or x16/x16 show conclusively, the difference is practically nothing, regardless of situation.

The notion that you should just get the most expensive you can afford is not necessarily true. The card I linked on the back page gives like 95+% of the performance of a 6870 for <85% of the price. That's a wiser purchase, for the 5% difference won't change the gaming experience, whereas the money saved might help somewhere else.

It's not that black and white, especially given the minimal difference of real world performance between the two.

Get the best card you can afford, no reason to go with something lesser. You can always sell it later (better card will hold its resale value better), you can SLI / Crossfire it later, whatever. With this in mind, I'd suggest the HD6870 over the HD6850. VRAM makes no difference at all seeing as how they're both 1GB cards, so get that out of your head. The stronger card is still the 6870 (painfully obvious even), why bother arguing about VRAM?

Or, if your budget can afford something from the green camp, might want to look into the GTX560Ti, GTX470's (they do run hot though), GTX480's (also hot), or even a GTX460 1GB (non SE model) / GTX560 (basically the same thing as a 460, the 460 should be cheaper).

There's also the HD6950 1GB cards that are right around that price bracket too.

My advice:
Don't skimp on your GPU, with the plan to SLI / Crossfire later. Get the stronger card now. You'll have less issues in the long run, and have an immediate performance boost. And yes, your PSU is solid and will easily handle a Crossfire / SLI setup of mid range cards (6870 / up to 560Ti / 460 included).

Thread Starter 

I don't want to start an NVIDIA vs AMD War here, I'd just rather stick with AMD.

I'm also only at 1680 x 1050, so that probably lessens my need even more

I'm leaning towards a 6850 at the moment, specifically:
http://www.ebuyer.com/264823-his-hd-...phics-h685f1gd

I only want to buy from Amazon or eBuyer, but thanks for the recommendations

I'm not worried about 16x/4x, from what I can tell, and what you guys say, It makes very little real world/in game difference.

EDIT:
Looks like I'm not quick enough with my replies
It appears I can get a Sapphire 6870 for just over £140:


Would this definitely be worth the extra in terms of performance and, to an extent 'future proofing' ?

Unless you're a super enthusiast or just someone who likes to experiment, I always also advise going for the best single GPU one can afford. When people start thinking of buying two midrange cards to make up for the lack of performance of having just one, they should also consider that maybe just one for a little more money can bring you the performance you need, along with no headaches from Crossfire incompatiblity with some games, or the constant CAP updates you have to install for games to work properly in Crossfire configuration.

The HD6870 is the best choice to game at 1080p within his budget. If he can afford a HD6950 2GB I would suggest him that, but he said he can't, so it's a non question.

It appears I can get a Sapphire 6870 for just over £140:
Sapphire HD 6870 1GB GDDR5 Graphics Card: Amazon.co.uk: Computers & Accessories

Would this definitely be worth the extra in terms of performance and, to an extent 'future proofing' ?
It's not about AMD vs. Nvidia, its about getting the best bang for your buck. If you can find a GTX460 1GB in that same price bracket, jump on it. It'll be at 6870 levels single card (the 6870 beats in multi GPU setups though).

Either way though, the HD6850 is a good card too. It won't steer you wrong either. I'd just like to see you get the biggest bang for your buck. I could care less what side of the fence the GPU is from.

EDIT: (Saw your edit just now):
Yes, the HD6870 is definitely a good bit faster than the HD6850. They both scale very well in Crossfire too, but the HD6870 is going to give you that extra power right out of the gate. It's about 10-15% faster as a guess. It's like comparing the HD5850 to HD5870, or the HD4850 to HD4870.

Get the 6870 for now..and later on use CF. You say you don't play much 'demanding' games right now because the 'kind' of games you play aren't that demanding yet....maybe next yr there be a game you will fall in love with but then realized the 6850 isn't strong enough. Also maybe you go over to your buddy's house and tried out Crysis 2 and thought dang i want to play that ... then realized you only got a 6850.

People complain that x4 is going be a problem, but in reality you won't lose that much performance.... CF is CF ... i read somewhere that SLI has more effect on the x4 than CF...but either way you going get increase in performance for sure.

I had CF 6870s ... they were amazing... sold one...waiting to sell the other one....just to upgrade to GTX 580 SLI or GTX 590. That just me... 6870s were good enough..i m just a power hungry person.... haha

To the OP, I'm gonna disagree and say no, you don't need a 6870, unless you don't plan on upgrading for another 2-3 years. Considering how much cheaper a 6850 is and how badass CF 6850s are if you do choose that route, and also the fact that you aren't planning on playing any games that a single 6850 can't max out, why not get the cheaper card?
post #20 of 52
If you can afford the 6870, then get it. I'd say get it only if you're going to keep it for quite a while. The 6850 will max out all the games you have listed.
