If you're looking for a Radeon HD 4870 graphics card that's a little sleeker than AMD's reference design, GIGABYTE's GV-R487D5-1GD could be just what you're after.

The recently launched graphics card is built on AMD's Radeon HD 4870 GPU but carries an in-house design that makes use of GIGABYTE's Ultra Durable 2 feature set - meaning high-quality power-efficient components - and throws in DVI, HDMI and DisplayPort connectivity.

In addition to the useful trio of connectivity options, there's 1GB of on-board GDDR5 memory and a custom heatsink and fan to help keep it all cool.

GIGABYTE has thus far failed to mention actual clock speeds, so we'll assume they're at AMD's reference levels - that's 750MHz and 1,800MHz for core and effective memory, respectively.

No word on pricing, either, but it shouldn't be long until this one reaches retail.

So if I were to have to a monitor and a GPU equipped with DisplayPort, what, if any, benefits would I see?

Well the display port header is a lot smaller :D

I dont think there would be any noticable difference for normal resolutions butwhen you start cranking up above 1080p the bandwidth limitations of HDMI/DVI may start to become apparent.

Edit: that as just a guess i checked out wiki out of interest

wikipedia
Advantages over DVI

1. Based on micro-packet protocol.
* Allows easy expansion of the standard
* Allows multiple video streams over single physical connection (in a future version)
2. Designed to support internal chip-to-chip communication
* Can drive display panels directly, eliminating control circuits and allowing for cheaper and slimmer displays
* Aimed to replace internal LVDS links in notebook panels with a unified link interface
3. Supports both RGB and YCbCr encoding formats
4. Auxiliary channel can be used for touch-panel data, USB links, camera, microphone, etc.
5. Fewer lanes with embedded clock reduce RFI.
6. Slimmer cables and a much smaller connector that doesn't require thumbscrews. Connector pins don't run the risk of bending if improperly handled.
7. The DisplayPort connector is easier to connect when guided only by touch.

Advantages compared to HDMI

1. DisplayPort does not require licensing or royalty payments.

Disadvantages compared to HDMI

1. No xvYCC color space support.
2. No Dolby TrueHD or DTS-HD Master Audio bitstream support.
3. No support for Consumer Electronics Control signals.

Didn't know either of those things about DP. Each of those could isolate certain users, meaning HDMI sticks around for a bit longer. (Having said that, a later rev'n of DP could add both of those features.)

eh, when they bring the same to 4870x2 I'll care - I was surprised that it didn't have HDMI when I first saw it.
