The Gainward Bliss 9600GT PCX DisplayPort Golden Sample came with my desktop pc when I had it built about a year ago. I let the pc guy pick some of the hardware for me and the graphics card being one providing it was a good one.
The Gainward Bliss 9600GT PCX DisplayPort Golden Sample is basically the Nvidia 9600GT graphics card with a few extras in the box such as a Tomb Raider game (the remake of the 1st)
The Nvidia 9600GT is PCIe 2.0 compatible which means that when paired with an identical 9600-based graphics card you can double the output.
Therefore you could have 2 512Mb graphics cards acting as 1 GB card.
The specs are
512MB Gainward 9600GT,Bliss GS, PCI-E 2.0, Mem2000MHz, GDDR3, GPU700MHz, 64 Cores, 2x DL DVI-I/HDMI
The card easily matches to those currently on the market from ATi and other leading brands. And as you can buy the Gainward Bliss 9600GT PCX DisplayPort Golden Sample for around £90 it is easy on the wallet.
If the card was paired with another it would become powerful enough to contend with some of the highest spec NVIDIA graphics cards which are sold for £350 upwards (NVIDIA GeForce GTX 295)
Overall this is a great graphics card and I personally will be buying another to double the output
