Introduction to the Gigabyte GV-R577UD-1GD HD 5770 Video Card

We all know AMD recently took the performance crown away from Nvidia with the release of the HD 5870 and HD 5970 graphic cards, a crown held proudly aloft by the Nvidia GTX 295/285. The honor holding it is often traded back and forward between the two. Iin order to experience the performance given by either of these cards means forking out $400 plus.

AMD is often known as the better price-vs-performance winner of the two, but not everyone is going to kiss this kind of money goodbye just to play a couple of first person shooters. To cater to people on a budget, here comes the HD 57xx series. They’re a nice alternative to the more costly offerings, which will play all the current games at better than average settings. Offering a lower cost card is one thing, but you have to supply the end-user with features as well. Granted, the HD 57XX series is not going to give you 1000MHz of Core Clock or even two gigs of GDDR5 memory.

How about DirectX11, Eyefinity monitor setups and Crossfire? Yes, all the HD 57XX models share these same features with the HD 58XX. For less than $160 plus the price of three monitors, you can have a visually awesomel setup

Closer look

The HD 5770 gets all the features and benefits of its bigger brothers, the HD 5850 and HD 5870. This includes the infamous Eyefinity technology. I will not get into the feature much as I am sure you have read about it on the various website that have experimented with it. In brief, the feature allows the user to hook-up three monitors to one HD 5XXX series card for the ultimate gaming experience.

What you don’t get with the HD 5770 that you do get with the more powerful cards is the size. The HD 5850 and HD 5870 each measures nine and eleven inches respectively. The HD 5770 comes in at eight inches making it idea for SFF cases as well as smaller HTPC enclosures.

For specifications the HD 5770 has some very decent ones. We begin with the core and memory clocks which are 850MHz and 4800MHz respectfully. This is right in line with the past generation HD 4890 which is still a very popular card. In reference the HD 5770 comes in two variations: a 512MB and 1GB models. Gigabyte themselves have three models all based on 1GB of ram. Based on reference and non-reference cooling designs.

The GV-R577UD-1GD which we as reviewing today has a non-reference coolers that has a serious love it or hate it sense about it. Personally, I was digging it. It is not a large cooler like we see on the higher-end models but a smaller plastic one that houses a 80mm cooling fan. Similar in shape of the Bat mobile the cooler on the HD 5770 does require dual slots. Underneath is an aluminum heat sink covering the core and most of the ram chips. Gigabyte decided to use a blue PCB the same color as used on their motherboards. This is good for Gigabyte fan boys who want things to match.

The rear of the card consists of two DVI, one HDMI and one displayport connection. In order to use the Eyefinity feature one of the three monitors must be connected to the display port. These types of monitors can be hard to find and once found could be expensive. So an secondary option is to use a powered DVI to displayport adapter. On the opposite end is a single 6-pin power connector. According to AMD, a 450 watt power supply is required or 600 watts when using Crossfire.

Devil May Cry 4
Long ago the Dark Knight Sparda rebelled against the dark emperor and waged a one-man war to save humanity. Thousands of years later, a religious organization worships this renowned savior and has taken it upon themselves to rid the world of all evil. Residing in Fortuna, this organization is known as the “Order of the Sword,” and is made up of an elite group of “Holy Knights.” One day, a young knight named Nero witnesses Sparda’s legendary son Dante slaughter his fellow warriors. Has the renowned devil hunter turned his back on mankind? What does the encounter mean for these two individuals?


Unigine DirectX 11
New benchmark grants the power to unleash the DirectX 11 potential in the gift wrapping of impressively towering graphics capabilities. It reveals the enchanting magic of floating islands with a tiny village hidden in the cloudy skies. With the interactive mode emerging experience of exploring the intricate world is ensured within reach. Through its advanced renderer, Unigine is one of the first to set precedence in showcasing the art assets with tessellation, bringing compelling visual finesse, utilizing the technology to the full extend and exhibiting the possibilities of enriching 3D gaming.

Capcom Resident Evil 5
Capcom officially announced Resident Evil 5 on July 20, 2005. Jun Takeuchi, the director of Onimusha and producer of Lost Planet: Extreme Condition, took over producer duties from Hiroyuki Kobayashi. Keiji Inafune, who served as promotional producer for Resident Evil 2 and executive producer for the PlayStation 2 version of Resident Evil 4, oversaw the project.[26] In February 2007, members of Capcom’s Clover Studio were also called upon to help develop the game.

Capcom Street Fighter 4
All the characters and environments in Street Fighter IV are rendered as 3D models with polygons, similar to the Street Fighter EX sub-series Capcom produced with Arika. However, there are a couple of key differences. Art director and character designer Daigo Ikeno, who previously worked on Street Fighter III 3rd Strike, added cel-shading to give them a hand-drawn look, with visual effects accented in calligraphic strokes, ink smudges and ink sprays during the fights.

Power Consumption

RELATED:  Cooler Master TPC 812 Vertical Vapor Chamber CPU Cooler

We used of trusty WattsUp meter to measured the wattage consumption of the various video cards we have tested in our reviews. Here we see the HD 5770 drew slightly more power than the HD 5750 we reviewed some time ago. A mere 22 watts on load.


We let ATI’s Catalyst Control Center to do all the overclocking. We see that letting the application auto-overclock we reach the maximum allowed. Taking the time to use RivaTuner and manually overclocking the card we may have been able to surpass these limits.


AMD has widened the distance between them and Nvidia with the addition of the Radeon HD 5770. Not in performance, but all the features this card shares with the bigger HD 5850 and 5870. DirectX 11 has given us the future proofing we want in a GPU and the Eyefinity options gives us a feature never seen before in a mainstream GPU. The card does not lack performance at all. Gigabyte assured us that with a great version of the video card with better than reference cooling. The Gigabyte GV-R577UD-1GD HD 5770 is a nice alternative to the reference models we see.

At $160 the Gigabyte HD 5570 is an ideal card at an ideal price. Offering all the advantages of the above and performance that is good enough to play the latest games at a very high reference at some levels of eyecandy turned on. This is because of the 850MHz core clock and 1.2GHz memory speed. And with all this we will not have to suffer through high electricity bills as the GV-R577UD-1GD power draw was just slightly higer than that of the HD 5750.

At the same price point you can elect to go the route of the Nvidia GTX 260 which Gigabyte has a few versions of. Granted these cards maybe a little faster overall especially with eye candy turned on, you do not get the added benefits of the latest Radeon cards like Eyefinity and DirectX 11. These two features along is enough to slay person to the red side.
