INSTALLATION & USER MANUAL

I am really happy with the performance of this graphics card. I already had 4GB of installed ram in my computer. But I did not have any graphics card in my system. So I bought this card. This card also supports dual monitor at a time. It works much better with windows Vista operating system (compare to XP) and all the additional features also support Vista. There is only one cooler on top of it and noiseless. To be honest with you, I was doing some extensive programming after installing this card and not once I heard any noise coming out from this. As it says that it supports upto 2500x1600 resolution, but it works better on 1024x768. I wanted to play some games selecting the highest possible resolution, but it did not work out well. This is very disappointing.

~Plus Points~

1. Cheap, reliable and handy graphics card.
2. Noiseless and extensive connectivity options.
3. High quality video play-back support.
4. It also helps to upgrade the low-resolution videos and to enjoy them in HD quality.
5. Manufactured on 55nm, so it consumes less power.

1. Does not work well with XP operating system.
2. You need to have a modern mother-board with PCI-e slot.
3. I could not able to play high- spec games properly in maximum resolution.
