Hey there. I'm trying to decide whether to switch to Nvidia (I know they're overall better cards) by getting a GTX 670 or to stay with my Sapphire Radeon HD 7850 and pick up a second one for crossfirex. This is my build:

NZXT Phantom 410 Midtower (Black)
Intel Core i5 2500k @3.3Ghz
Corsair H80 Liquid cooler
Corsair TX750M power supply
ASRock Extreme4 Z77 mobo
Sapphire Radeon HD 7850
64gb Samsung 830 series SSD
1TB Seagate Barracuda @ 7200 rpm

I was thinking about getting another 7850 and crossfiring them, but then I thought about just getting a GTX 670 and then saving up to get another 670 and SLI-ing them. I know 2 670s is by far better than 2 7850's, but I'm looking to get something soon, and it would be a while before I could get the second 670. So as of right now, would 2 7850's outperform a 670?

Cheers

well two 7850 will easily outperfrom a single gtx 670 but if u have money then go for gtx 670 or not then 2 7850 is excellent choice

Performance wise, 7850 in CFX will be faster than the 670. But Personally, I am not a fan of Crossfire or SLI Configs so, I would rather recommend getting the 670 instead. But if you want to save more money and get other parts, no problem, get the 7850 CF, but be prepare to have driver and heat issue :) .

1-"I'm trying to decide whether to switch to Nvidia (I know they're overall better cards)"

2-"I am not a fan of Crossfire or SLI Configs "but be prepare to have driver and heat issue "


1-No such thing,they BOTH do the same thing.

2-Crossfire/SLI is for enthusiasts,people that know how to set them up properly.Not to mention a lot of games arent coded properly for dual GPU's.

either way,even I would suggest buying the best single card you can afford.It usually comes down to money,I always buy 2 highend cards for crossfire,never 2 lower end cards,but thats just me.

To OP:

Really?

Alright, let's put it up in a formula:

HD 7850 <- GTX 670 <- HD 7870 <- GTX 660Ti "Power Edition" <- HD 7850 x2 CFX <- HD 7950 <- GTX 580 <- HD 7870 x2 CFX <- GTX 590 <- GTX 670 x2 SLI <- HD 6990 <- GTX 690 <- HD 7970 "R7970 Lighting" <- GTX 690 x2 SLI = Get 7870 or GTX 660Ti "Power Edition" from MSi, or (if you can afford it) get one HD 7950 from Sapphire.

Umm.. Really?



Yes this is the factory overclocked 7850 Iceq X Turbo X model. But stock 7850's shouldn't be very far from this.

Who said anything about IceQ? Also, it's OverClocked AND in CFX, duh.

They probably would.

Ugh... No point arguing with you. WE ARE TALKING ABOUT 7850 in CF! duh. I was saying That you're wrong on the way that you say the 7850 CF is between 660 Ti and 7950... It is the same as 680 or faster. Maybe I showed you a 7850 IceQ X turbo X. It is just a 7850 Overclocked to 1GHz with non Reference cooling in crossfire. So the result may be 10% less with the 7850, which is still faster than the 680...

And your chart is wrong.

7850>580>7870>660Ti>7950>670>7970>590>680>7850x2>6990>7970GHz>7870x2>670SLIx2~690

You underpower CF and SLI configs. It performs really good but you have hassles :) .

Okay, so you're saying a 680 is better than a 7850? I don't believe that. And is the 660 Ti even out yet?
August 20, 2012 11:43:46 PM

Well You don't understand what I said. I said, 7850x2 is better than the 680, but the 670x2 is roughly the same as the 690 :) . Yes the 660 Ti is out.
