6870 crossfire overkill?

Hi! I have the thought about buying another 6870 and get a crossfire setup. Will this be a overkill for my system and resolution?

AMD II x4 955 @ 3.2GHz
Kingston ValueR RAM 4GB 1333MHz
Silver Power 750w Modular psu
Gigabyte GA-970-UD3 Mobo
Cooler Master HAF X
Western Digital Caviar 500GB Hard disk
AMD Radeon 6870 @ 900Mhz
I will then buy a XFX Radeon 6870 "Dual Fan" card.

I play on a 1680 x 1050 resolution.

Is this a overkill? Will I max out Battlefield 3, Metro 2033 and such at 60 fps? Or should I just stay with my 6870 and not crossfire?

Sorry my bad English, my native language isn't English!

Thanks

CF 6870 would max out those games pretty easily at that res.

Maybe a little bit overkill, but it will still be a worthwhile upgrade. You might want to OC your processor a little though, since it might be a little bit of a weak point. Is your 6870 a 1 or 2 GB model? In games like BF3 you could run into a vram bottleneck. If not though you can get 60 FPS for sure.

At that res 1GB of of vram is enough.

Probably true, for some games I'm not positive.

Really there is no over kill because you still need more power for if you are wanting to play the real stickler games like Metro and Crysis, The Witcher 2, BF3, Batman AC etc and there will be many more to come in 2012 and beyond that will push even the highest end GPU setups of current.

There's overkill if your CPU is a bottleneck

I run 2x5850 (a little slower than 2x6870), and it's definitely not overkill for BF3 and Metro. Metro I run at near max settings at 1920x1200, but BF3 I only run high textures, medium shadows, high FXAA, 2xMSAA, 16xAF, HBAO to maintain +60 fps. You'd have a little strong GPU setup and a little lower resolution, but I still don't think you max BF3.

My recommendation, go for it.

What Koolg said, it's not overkill for that resolution, but it is for your CPU, at least on some titles.

Just want to let you know that I had an AMD 965 and 6950 both overclocked if you think adding another 6870 would be overkill ur right and wrong. I buildt another system with an I 5 2500k at 4.6 with a 6950 and got a massive fps increase. Sometimes its not the gpu its the instruction sets that Intel obviously has the upper hand with. WAs AMD for a long time. Never again

Yeah, depending on the game, you'd be real close to a CPU bottleneck... not to mention it'd probably be time to throw in a bit more RAM. I'm digging my 6870's in CFX though, you'd be able to max out everything out there pretty easily assuming the CPU keeps up.

I have a 6870 crossfire with my Phenom ii x4 965 @ 3.8ghz and I have problems trying to fully utilize both cards in BF3.I also have a resolution of 1600x900.I dunno if it's because of my processor or if it's just a driver related thing but I'm considering returning one because I'm not happy at all with the performance i'm getting.Something to think about maybe.

I think the way the Frostbite 2 engine works is it depends on the architecture of the CPU not how fast or how many cores it has just as long as it's a quad.But I still don't know for sure.I've seen a couple other people with similar setups as me but still get 100% usage from both cards.It just pains me because you spend close to $400 for a crossfire setup but your only getting $180 worth of performance.I think it's just one of the hassle's of running a crossfire setup,hit or miss.Which is why everyone says always go with the stronger single card solution.

Somehow I can't say I have had the same experience because all I have seen in my CF and SLI setups on a Phenom II chip is great frame rates and I can't use anything over 60fps anyway. http://www.guru3d.com/article/radeon-hd-7970-cpu-scalin...
