Eyefinity Flexing, Testing Methodology and System Setup
Of course we spent some time using the Sapphire Radeon HD 5770 1GB Flex card on a triple panel configuration and it worked without a hitch.  In fact, the driver and system acted exactly as if there was an active adapter at work between the card and the monitor – because basically that is what the Analogix chip and the Sapphire design are emulating. 

Sapphire Radeon HD 5770 Flex Graphics Card Review - Easy Eyefinity - Graphics Cards  1

If you are familiar at all with Eyefinity and NVIDIA Surround, you know the pros and cons of these configurations.  The only drawback I see to this implementation is that the HD 5770 is not really the most powerful card, and not the one I would have picked, to be the first to receive the “Flex” treatment.  Surely an HD 5870 2GB model would be the most ideal for an upgrade like this.  From what I can tell the HD 5870s are still selling welling enough that there is no need to differentiate to stand out from the pack but the same cannot be said for the HD 5770 cards.  Sapphire is hoping to see an increase in relative sales to its competition with the Flex option in place.

The Sapphire Radeon HD 5770 1GB Flex runs at the reference speeds of 850 MHz core, 1200 MHz memory

For our testing today of the performance of the Sapphire HD 5770 Flex we will be comparing it to the Radeon HD 5750, GeForce GTS 250 1GB and 768MB version of the GeForce GTX 460 graphics card.  To be fair, the GTX 460, even in its 768MB revision, is $190 in the current market while the Sapphire HD 5770 Flex will run you $150.  The HD 5750 is still selling for about $130 and the older NVIDIA GTX 250 1GB cards are still on Newegg.com for $120.  It would make sense then, if everything falls into line as it should, that the GTX 460 will be the fastest graphics card in our graphs but at the cost of another $40 to the user. 

Here is the test setup for our review: 
  • Testing Configuration
  • ASUS P6T6 WS Revolution X58 + nForce 200
  • Intel Core i7-965 @ 3.33 GHz

  • Intel X25-M G2 160GB SSD
  • PC Power and Cooling 1200w Turbo Cool PSU
  • NVIDIA Driver version: 258.96
  • ATI Driver version: 10.6 + CrossFire X update
Let’s get to the benchmarks!!
