I found another Packard bell with 8800 GTS except it's over £1000 ($2000) so too expensive but I found out that I can buy the graphics card separate and it works out cheaper : Here is the expensive computer specs:
* Intel Core 2 Quad Q6600 Processor
* Windows Vista (R) Home Premium
* 320MB nVidia Geforce 8800GTS Graphics
* 8800 GTS Nvidia graphics technology with DirectX 10
* 640GB Hard Drive + 250GB Portable Media Drive
* 2048MB DDR2 RAM
* Multi-Format Dual Layer DVD Rewriter Drive
* 8-in-1 Media Card Reader
* 6 USB Connections
* 2 PCI Slots, 1 PCI*16, 3 PCI*1
* Water Cooling System
* 22" LG Widescreen TFT
Wait a second! The 8800GT is a better performing card than the 8800GTS 640mb version. It is also cheaper too.
There is a new 8800GTS 512mb card that is going to be released some time this month, so I would wait. The new GTS is supposedly on par with a GTX from the benchmarks that I've seen.
