I am currently stuck making a decision and I would like some help My system specs are AMD Phenom IIx4 3.0ghz, M5A97 Asus mobo, 8gb HyperX Ram 1333mhz, Seagate 500gb HDD, Antec Green Efficient 500w PSU, Raidmax Atlas Case, gpu temporarily until I return it to best buy is a xfx Radeon 6750. For some reason the 550ti i originally purchased would not work with my system idk y just didnt. To be able to use my system I ran to best buy bought a 6750 that i will return once i make a decision (good idea if you have the cash to see if your video card is causing the errors or your system). Now the 550ti was on sale for 109.99 and from research is slightly better than the radeon 6770. At the time they were the same price. Here is the dilemma radeon 6850 is currently on sale for 139.99 gigabyte no less. But the sapphire radeon 6770 is 99.99 89.99 after rebate (6850 is 119.99 after rebate) both of which i have to wait 30 days before filing. I know gigabyte is usually awesome sauce when it comes to warranty's RMA's etc but I do not know much about sapphire. That is my first question which company is better or are they equal in customer service. Also will i get better performance from one 6850 or crossfiring 6770s? Thanks for any input on this dilemma. Notice my mobo is crossfire able. Thanks again.

by the looks of your sig i can tell that you have already decided in buying the sapphire 6770, taken that your PSU is 500w that would be insufficient for crossfire, but it is worthy to note that 2 6770's crossfired would be more capable than a single 6850(in my opinion) and actually it is not entirely true that the 550 ti outperforms the 6770, it depends on the game for each has an edge in each one :)

Xfire 6770 would whoop the 6850.
The antech 500w will power 2x6770.
The 6770 uses 108w at max load leaving 284w to power the rest of your system which is more than enough. Good luck in whatever you.choose

You seem to already have the 6770, which means you only have to buy one card and 6770 Crossfire will beat 6850.
If me, I will just crossfire your 6770.
Sapphire is a good brand, go with it.
Antec EarthWatts 500W has 2 PCI-E connectors and Dual 22A in the +12V rail. So I think it's nice and enough for 6770 crossfire.

That's my recommendation, but your pick is up to you, because when you get a 6850, you can crossfire it later and totally outperform 6770 crossfire. Just a good luck from me :) .

EDIT: MAKE SURE YOUR CARDS ARE CROSSFIRE COMPATIBLE :) .

I should've researched more about the ASUS EAH6770 because I just recently discovered that it is crossfire-incapable(after i bought it, because in AMD website they said that it was xfire capable! :pfff:  ), well the GPU is but they don't have those connectors where you can bind it to another card, but it was because I also thought that xfire will not be important to me because I only have a 500w PSU :(  now i know that it is enough, because there was no need to upgrade any other components at all if only I thought this through properly because:

1. If I had researched some more, I would've went for the powercolor version instead of ASUS, because I am pretty sure it was xfire-ready, by then I would've only been able to just buy another 6770 for better performance than buying a card a bit higher (2 6770 cards price vs. 1 6850 == a few dollars gap but the prior being more powerful) I guess i got too caught up with the cooler looks of the ASUS and now I have learned my lesson, looks aren't everything :sweat: 

2. In the event of an upgrade I would only need to change my mobo to one that has 2 PCI-e x16 slots :( 

But at least now I am happy in the knowledge that a 500w PSU can totally fire up 2 6770's, but in my set up now, I guess I'll go for a single card that is a bit higher. :(

Actually two Crossfire 6770s would be head to head with a single Radeon HD 6850, with the complications of Crossfire compaitblity, because the 6770 are basically a 5770 (same Juniper XT core) and they both have 128-bit memory interfaces which severely hamper it's capabilities.

So yes, you're better off getting a single Radoen HD 6850

A Crossfire configuration that would be a step up from a single 6850 goes way back to the Radeon HD 4870 series (no DirectX 11 support though)

In summary

2x 4870 (or 4870 X2) > 6850 > 2x 6770s/5770s

dont waste your time with a 6850 if you want a setup as powerful as the 5770x2. get a 6950 2gb you will be happy you did.
the 5770/6770 xfire is more along the lines or the 6950 or 560Ti in terms of performance

Did you just make this up or something instead of actually researching?

i second the motion, because 2 x 6770 == 6950 from what ive researched :)  so it would be a lot of a step up from the 68** series

well i went away from the 6770 at the end bc my mobo is x16 x4 which would only increase my performance barely I instead chose the 6850
