HD6870 Crossfire or HD6970??

Hey guys...help make up my mind while I still have the chance to exchange items.

Currently I have an i5 2500K build..I bought a Sapphire HD6870 and I plan on getting BF3 & MW3 once they're out for PC...I want to be able to play pretty much full throttle on my 1080p TV...i don't want to be just barely over the acceptable FPS..like 35/40...want higher.

Do I just keep the HD6870 that I paid $159 after rebate for cuz it will be fine...or do I future proof (if that's even possible) and return the card, buy TWO new HD6870s and do a crossfire setup OR buy ONE HD6970??

I'm thinking just do the crossfire 6870's cuz it would be better than a single 6950....or save space and have as good or better performance with one 6970.

But then do I have to upgrade my Corsair 650W PSU? Says it needs 600W to run 6870 in crossfire.

I'd like to order the new cards within a few hours so i can do free 2 day shipping and get on Friday :) 

Thanks guys :)

Do the crossfire...unless you plan on getting another 6970 in the future to cross fire. What's your psu at now? 650 minimum is defi recommended for crossfire...

You can use the extra money to buy the new psu as well, you should save ~$100 with the 6870s

First off if you stick with the 6870 i personally wouldn't return it and buy the othere just for the rebate they some times are so difficult to complete most people don't do them and at best you'll be waiting a few months.Your PSU should be fine earthier way Corsair is a great company that a good PSU. Two 6870 will be faster then a 6950 for most games but more power and more heat. Knowing that its mostly a matter of choice.

BF3 is a true monster. With that said, I have two Sapphires in crossfire on my 750 watt machine. I decided to build a new system with 2 580 cards in SLI at a much greater expense than to do another crossfire.

Do not feel rushed to beat the clock when making purchasing decisions. You will find that Crossfire properly fed with a strong power supply will do very well. But will it take a game to the max? Well... let's just say that as long as my kills are greater than my deaths.... I'm happy. I treat hardware as a form of warfare right there with the game itself. The stronger, the better.

Well...i really wouldn't have a problem returning and going SLI with a couple nvidia cards if those are supposed to be better.

I realize 6870's aren't top o' the line but I'm ok with that. As long as I can play with decent smoothness I'm happy.

Yes, i have a 650W PSU right now...but wonder if I should just go 750W even if 600W is rated fine for crossfire 6870s...yeah, don't want to rush it but i get too excited..lol

I bought at amazon..they're cool with returns. I would buy the new parts and then send the old parts back. I can ship from work so no cost to me.

Well MW3 will be max'able with an old card like 8800 gtx.

For bf3 its more cpu dependant, you're 2500k is really nice for it, i would go for a single card like 6970 and overclock it a lil and you will pretty much be able to play BF3 near max with 4x AA with 50+ frames

If you decide to go for 6870 cfx the corsair is fine for it, corsair make the best psu's

Crossfire two 6850s and you'll significantly outpace a single 6870, you'll only have to utilize (2) 6-pin connectors. It is a middle ground between the single 6870 and two 6870s xfired. The 6850 in crossfire were made to scream and will easily handle BF3 and MW3...and only set you back 250-300 bucks. I picked up one 6850 HD OC on geeks.com for $129.99. You're only averaging about 245 watts of juice with the two 6850s as well and only requires a 650W PSU. Not a bad bang for your buck if you ask me.

Yeah, I saw amazon had the HD6850 for 149 after rebate....2 for $300 is a nice number plus the other savings.

Ugh...i hate these decisions!!

Then, if you think a single HD6870 won't be enough, send it back for a single HD6950 or HD6970.


a little busy at work right now but saw the gist of it and will definitely read it over! Thanks!

After reading that stuttering article I think I'll pass on a dual set up.

Now I'm wondering if its worth upgrading from my 6870 1GB to a 6950 2GB with Dirt 3 and Deus Ex "free"

The 6970 is just a little too pricey for me.

$159 for the 6870 after rebate....$244 for the 6970 for slightly faster speeds, 2GB of ram and 2 free games...i love racing games too and wanted Dirt 3 anyway.

Seems the 6950 is usually only about 3-10FPS faster...that really even make a difference?

Would you spend the $85 to upgrade? Isn't having a card with 2GB ram better than 1GB...and makes sure my card is a little better down the road for even more graphics complex games?

As of now my highest playable res is 1920x1080 on a plasma hdtv

The 6950 isn't a worthwhile upgrade from a 6870, it's only about 10% faster, yielding an improvement of 3 to 10 FPS in most circumstances. The 2GB version shows no better performance than the 1GB version unless you are gaming across multiple monitors, or a single monitor with a very high resolution eg. 2560x1600. The 2GB version might be slightly more futureproof, but given the performance boost you would get with the 6950 over the 6870, it simply isn't worth it. You're probably best off sticking with the 6870 for now and waiting until the HD 7000 series and see if any of those cards will offer a worthwhile upgrade. At your resolution you would only notice a difference between the two cards on a few of the more demanding titles, and even then, the amount of money you'd spend wouldn't be worth the extra 10 FPS.

Thanks Supernova...deep down I knew that was the case but was trying to tell myself that 2 free games and a little better FPS would be worth it and I ended up ordering it..lol. After reading your post I tried to cancel my order thru amazon but its already been shipped...i'll just refuse it from UPS when I get as per Amazon's tips for returning it.

Now a moral conundrum....I already got an email with my code for a free copy of Deus Ex: Human Revolution for "buying" this card....do I download it knowing I'm returning the card? lol.
