OCWorkbench take a look at this card:

Gigabyte GV-RX387512H-B is it's first AMD HD 3800 series graphics card to launch on the announcement date of the AMD HD Radeon 3850 and 3870 graphics card.

With a new RV670 core, it will be able to do better than it's previous generation cards. Some of the new changes made to the RV670 core includes the transition to 55nm manufacturing process. This generally allows the card to scale in performance and generate less heat. The HD 3800 series also features the support of DX10.1 and Shader Model 4.1. This includes 32-bit floating point texture filtering, Indexed cube map arrays, Independent blend modes per render target, Pixel coverage sample masking Read/write multi-sample surfaces with shaders, Gather4 texture fetching.

Read the full review at OCWorkbench:

Memory bandwidth has always been one of the bottleneck in graphics systems. The HD Radeon 3800 series now comes with PCI Express® 2.0 support, which allows up to twice the throughput of current PCI Express® cards. It  doubles the bus standard’s bandwidth from 2.5 Gbit/s (PCIe 1.1) to 5 Gbit/sec. Transfer data up to 16 GB/s.

The card also supports ATI CrossFire X allowing scale up rendering performance and image quality with two, three, or four GPUs on supporting chipsets like the AMD 790FX.

For those who are into High Definition Video playback with H.264/AVC decoding, ATI AVIVO HD supports universal connectivity to TVs and displays using HDMI with 5.1 surround sound. The card supports Unified Video Decoder (UVD) for Blu-ray™ and HD DVD and ATI PowerPlay™ energy conserving technology.

The Gigabyte GV-RX387512H-B based on the HD Radeon 3870 GPU comes with 320 stream processors and has a core clk of 775MHz and memory clk of 2400MHz. It has 320 stream processors and the memory bus is 256 bits. The card comes with 512MB GDDR4 (16Mx32).

The card comes with DVI Port DVI-I (Support Dual-link DVI), TV-out,AV out HDMI (by optional adapter) and is HDCP enabled.
