The Radeon HD 4800 series video cards are currently available in three flavors; the 4850, 4870 and 4870 X2. The single GPU HIS HD 4870 512MB GDDR5 Video Card is based on the RV770 core which is built on the 55 nanometer manufacturing process and has 956 million transistors. The core speed on this product is 750MHz and the 512MB of GDDR5 256 bit memory is 3.6GHz DDR. It comes with 800 stream processing units for vertex, pixel and geometry data, 40 texture units and 16 raster operators. The pixel fill rate is 27 GPixels/sec and the memory bandwidth is 115.2GB/s.

The HIS HD 3870 X2 1GB GDDR3 Video Card is based on two RV670 cores (2xRV670 = R680) which are built using the 55 nanometer manufacturing process and has 1.332 billion transistors. The core speed on this product is 825MHz and the 1GB of GDDR3 256 bit (x2) memory is 1.8GHz DDR. It comes with 640 stream processing units for vertex, pixel and geometry data, 32 texture units, 32 raster operators, the pixel fill rate is 26.4 GPixels/sec and the memory bandwidth is 115.2GB/s. Performance on this Video Card is out of this world!.

The Silverstone Olympia line of power supplies are available in wattages ranging from 650 to 1200. I’ll be reviewing the Silverstone OP1200 1200W model which is more than enough power for even hardcore computer systems. The housing is steel and they include a very quiet 135mm fan which is recessed, but this PSU is extremely long so it might not fit in some smaller mid-tower cases. Also note that this fan is load controlled, meaning the more load on the PSU the faster the fan spins. Watch the video to find out more and check out the bloopers at the end.

I’ve reviewed many TV Wonder products and they’ve all been very good, but AMD’s ATI TV Wonder 650 Combo PCIe x1 takes the cake! Why this TV Tuner product is exceptional has mostly to do with the 650 Pro chip. This particular product has two tuners, one tuner is responsible for receiving analog TV channels and the other receives digital and HD channels. It’s also capable of receiving FM radio. I should also note that the 650pro chip doesn’t require any cooling, so it’s a perfect option for a silent HTPC. Watch the video to find out more and check out the bloopers at the end.
