MSI R6770 Twin Frozr II/OC Radeon HD 6770 1GB 128-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card

Pros: 1. Stays at decent temps depending on the ambient room temp. Twin Frozr, is pretty epic.
2. Plays a lot of the higher demanding games.
3. Can barely hear it (although I run an AC 24/7.)
4. Still going strong (touch wood) since the date of purchase.
5. It was cost efficient.
6. If you're into it, Aesthetically speaking, it's quite appealing.

Cons: 1. Does get outrageous in terms of idle temps depending on ambient room temp.

Other Thoughts: This is an efficient cost friendly card that enables a lot of the higher demanding games to be played. To date, I can play GW2, FireFall, and various similar demanding games with decent Frame Rates. Of course, this does change depending on the scenario.

In GW2, more often than not in those big group events (think of Shadow Behemoth/Dragon) the lag does start to kick in, and the game starts showcasing 10-20+ Frame Rate juggles. Granted, this is with Medium-High settings on most of the functions, and with V-Sync. In medium groups, I tend to see 30-50+ Frames.

FireFall, same deal. The group instances tend to get a lot more hectic with lag - but then again, that's with a lot of the 20-30+ people all at once type events and scenarios. Other than that, I can play the game quite smoothly without those huge incremental occurrences of drops within Frame Rates.

Pros: -Price
-Getting 59-63 fps on Starcraft II with settings on Ultra.
-This thing is great! I might get another for a Crossfire setup when Diablo 3 comes out, but I may not even need it.

Not sure what the acceptable temp range is for this GPU, but mine runs in the mid to upper 50's to low 60's (Celcius) without issues.

Cons: None so far

Other Thoughts: -AMD FX-6200 - OC @ 4.0 GHz
-Cooler Master 212 Plus
-6 Gb Kingston DDR3
- MSI R6770 Twin Frozr II/OC
-Gigabyte GA-990X-UD3
-MushKin 120Gb SSD
-550W Antec PSU

Pros: I have this working crossfire with the 5770 model along with an AMD Phenom II X4 945 and Crucial Ballistix 4GB 240-Pin 1866. These allow a game like Battlefield 3 to run smoothly in very high graphics mode. A little glitchy in ultra.

Cons: At first I thought it was the cpu cooler making the noise but the cards are what did it. Each card has two fans. Definataly not a deal breaker.

Other Thoughts: For this price, I am surprised at it's performance.

Pros: Very quiet, Stays cool (never breaks 50c), Crossfire performance is amazing with the right drivers

Cons: There are higher bench marked cards in this price range this is not really a con and this card is worth every penny. also the power consumption of the other cards in this price range is very high in comparison.

Other Thoughts: So i built a new gaming system consisting of
Gigabyte 990fx ud3 MB
AMD FX 8120 8 core Processor
x MSI R6770 twin frozr cards
16gigs of ddr3
intel SSD
500gb storage drive
antec 620 liquid cooling
antec lanboy air case
a 700 PS
as well as some other components.

When i originally started the build i was not planning on using crossfire. but did some research on how to hit the bench marks i wanted to get to without spending tons of money and decised to mid range cards was the way to go. I found that 2 6770 cards would work well with my limited PS that i had already purchased. they work great and it cost me half of what a single card would to get the same performance.

Pros: For me this card screamed out of the box!!! Very easy install. Quite an upgrade from my HD 3450!!! Plays everything I throw at it with NO issues!!!

Cons: Not a con really, Had to download newest drivers, as the one on the disk was outdated!!!

Other Thoughts: In my current case, wires are everywhere and airflow is a problem! Waiting for my new case now, but this card is running strong at 38 celsius (100.4 F) and i have it clocked higher than it came!!! Insane!!!

Pros: Looked great, has good benchmark scores.

Cons: When I first put it in, it made a horrible noise, then stopped. One of the fins was damaged & wound up breaking off. Once the fin broke off, the noise stopped & it hasn't seemed to affect it much. If you even touch the back of my machine, or move my machine (it's on wheels - the HAF 942 - so we're not talking jostling, just moving forward to see the back of it) the whole monitor blacks out due to the card. Can't even touch it in even the slightest. Guess I expected it to be a little more sturdy than that.

Other Thoughts: No, I won't RMA it - installing the blasted thing was enough of an adventure for me on my first machine. It was more of a pain (had to use the support pieces that came with my case) than putting together everything else combined. Make sure you have a way to support this card, it's quite heavy.

Pros: I am very happy with this card, excellent card from MSI like always. Compared to the 5770 twin Frozer this card isn't much different. But that is a good thing because the MSI 5770 was amazing! The packaging, all around quality makes pretty glad I chose msi above the other brands.

Cons: Well it is only as good as it gets for this series. If you spend a bit more you can get something a good deal more powerful like a 6870.

Other Thoughts: I would advise doing your research on benchmarks to make sure your okay with the performance you are getting. It's not bad, you can play pretty much any game out there on this. However some things (bad ports most of time) you will have to turn down a few settings. I figure most people in this price range usually don't mind that.

Pros: - Fits well with MSI 880gma-e35. The vid card goes over 4 of 6 sata sockets but I was able to use 3 of the four.
- Quieter than my cpu fan.
- Perfect fit for a lian li v352 micro atx case.

Cons: The 6850s are almost the same price.

Other Thoughts: I read in the reviews it's as strong as my old 4870. Still bought it because I was more interested in getting it to fit in the case.

Pros: Great performance for price
Stays super cold
Look awesome in your case
Not too budget busting
Quiet until you get over 70% fan speed (which you probably never will have to)

Cons: Compared to some of the other 6770s it is kind of pricey, but the cooler more than makes up for it.

Flimsy. As said with the 5770 version of this card, the main board of the 6770 is also pretty flimsy. Once its all installed and secured the one corner not supported droops down more than I would like. I feel like if my comp got kicked or something it would snap off lol.

I ordered this and the next day they made it so you could get Shogun2 AND Dirt 3 instead of just shogun, not a con but kind of meh.... So make sure you buy the Shogun 2 combo (if its still available) and it should auto add the dirt 3 game as of 8/22/2011

Other Thoughts: First off this card stays super cold even when overclocked.
Core 940 and mem 1300 clocks stable on stock voltage.
never saw over 51c under full load in furmark !WITH ONLY 35% FAN SPEED! I cranked it to 100% speed, which wasn't even that loud, and couldn't even break 40c under full load.

Rosewill Stallion Series RD600N-2DB-SL-BK PSU

3Dmark11 score of about p2800
3DmarkVantage score just over p9000

Crysis 2 1280x720 "advanced" graphics setting = 30-40fps (gamer = 40+ consistently)

WoW Cataclysm 1920x1080 ultra (4xAA+sunshafts off)40-60 FPS depending on area.

BF:BC2 19020x1080 High (1xAA) 35-40fps average(50+ spikes)

Source engine games 1920x1080 highest possible settings 60-100+ fps

All in all this is a really good card for the money. If you could afford to get a 6790 or a 6800 series I would do that tho.
