Asus Engt430
 

When push came to shove, the ENGT430 was able overclock and saw an increase of 166MHz or close to 24% in core clock speed while the memory fared a bit worse at 900Mhz or around 12.5%. These increases were stable and allowed the gaming performance of this card to be increased across the board and this allowed it to be extremely competitive with the HD 55XX series from ATI.

The ASUS ENGT430 features the Nvidia GeForce TG430 GPU (based on the GF108 Fermi GPU) running at 700MHz and 1GB of DDR3 memory. The memory is clocked at 1600MHz and is on a 128-bit interface. This card is ideal for HTPCs with its low profile design, allowing it to fit into thinner cases with the included optional mounting brackets. While the ENGT430 is primarily geared towards a life in the multimedia world, it still packs a punch in the 3D graphics arena, with entry-level DirectX 11 performance.
