Most of the testing consisted of playing with the Eyefinity set-up without an active adapter, the Eyefinity setup was without any issues.

Conclusion:

This card will give you the the value of the HD5770, and you won't need an active adapter for Eyefinity. This could also be a perfect card for companies looking to run triple or quad monitors for their employees.

Compared to:

• ATI Radeon HD4870
• ATI Radeon HD4870 Crossfire
• Diamond Radeon HD5770
• GeForce 8800GTS G92
• Gigabyte HD5770 SOC
• Radeon HD 5550 Ultimate
• Sapphire HD5550 OC
• Sapphire HD5670 Ultimate
• Sparkle GTX 260

Installation: Installation only requires a 6-pin power cable, while the Radeon HD 5870 needs two. The HD5770 Flex doesn't require an active adapter. It's recommended to download the most current drivers directly from ATI.

Performance:

In 3D Mark Vantage it was just below the reference HD5770 that had a somewhat higher result. Bad Company 2 slowed down in Eyefinity to app. 15 FPS.

Overclocking:

The reviewer did not perform any overclocking.

The moniker FleX can support up to four monitors in ATI Eyefinity by using three DVI connections where one is a HDMI to DVI adapter. The card itself runs at stock reference speeds of 850 MHz GPU core and 1200 MHz GDR5 memory.

Conclusion: Although this card is just a 'reference 5770' with a different heatsink, it has a lot of overclocking headroom and remains cool. Being able to benchmark @ 1 GHz for the GPU core is not an insignificant feature, and there was probably the possibility for more overclocking headroom. Using three monitors together for ATI Eyefinity with 3 DVI connectors is a nice bonus.

Overclocking: The GPU core was OCed to 980MHz and the memory @ 1360 MHz, that is 130MHz (15%) more for the GPU core and 160MHz (13%) for the memory.

Test Setup:

• Computer Case: Hiper Osiris
• CPU : Intel Core i7 920
• HDD: Seagate 7200.12 1TB
• Mainboard : MSI X58 Platinum
• Optical Drive : LG DVD RW
• OS: Windows 7 Professional x64
• PSU: Mushkin 800 watt
• RAM : DDR3 1600MHz Mushkin Redline 6-8-6-24

Compared to:

• ASUS ENGTX465
