The nVidia GeForce 8400 GS is a great little entry level card. Though it has been passed by two full generations of newer cards that fill the same entry level requirements (Ati 4450, 5450 and the GeForce 9400, 220 and low end 400 series). This card is still relatively competitively priced if all you want to do is play movies and enjoy some older games. It is fully supportive of direct x 10.0, and as such, had huge numbers sold as a cheap graphics solution for the early period when windows vista just came out. In 2007 I paid £38 for it. The clock speed is around 450 MHz and it has 256 mb dedicated ddr2 ram memory operating at a standard 800 mhz speed. The ...  Read the complete review

I recently purchased this Graphics Card for next to nothing from eBay; it was £12.99 which seemed like incredible value for such a card. It is a modern specification card, designed for the latest generation of Windows Operating system (Vista and 7) but I use the card with the trusty Windows XP. The card installs in the PCI-E x1 slot, not the x16 slot as others have mentioned. This poses a slight problem as some old motherboards do not support this interface as well as extremely new motherboards carrying only the higher bandwidth PCI-E x16. Before purchasing make sure you find out what motherboard you own and check its manual to make sure the slot is ...  Read the complete review

Although the graphics card is officially a 256MB, my computer and games that I use all read it as a 512mb graphics card, so im not quite sure what it is, although i'm happy at viewing it as a 512mb. The graphics card runs on DDR2 RAM. For a start the graphics card is nice and cheap, will probably cost you £25-£30 if you look around on the web, well worth it considering how well it will run most games, only the most recent games will have trouble running. It will run games such as Call of Duty: Modern Warfare 2 on minimum. It has Vertex and Pixel shader 4.0, which is pretty much what all the recent games require. It also supports OpenGL version 2.1 ...  Read the complete review

I bought this graphics card last year to replace an old one that came with my PC. Its not the newest or most powerful graphics card around but it does its job. Brand new games that are coming out now (Q3 2010) are too powerful for it to run, but games released in early 2010 and before should run on this graphics card, if you tweak the settings. Although the graphics card is advertised as a 256mb, and when you boot up your PC it displays it as a 256mb, video games and the DXDIAG function both read it as a 512mb card. Im not sure which to believe, but it seems to be able to run games requiring a 256mb card with no problems, so im more inclined to believe its ...  Read the complete review

The 8400GS may be showing its age now, but that perhaps works in its favour - it is very cheap to buy now, and for a beginner looking for a quick and effective upgrade to their system, this is a great choice. As with any graphics card, physical installation is fairly simple - just open up your desktop, plug it in, and providing the correct drivers have been installed beforehand, it should start working immediately - I had no problems when installing mine. Depending on the PC you have, you will probably see different jumps in performance - personally, installing this card into a HP Pavillion PC, there was a very noticeable improvement in performance ...  Read the complete review
