Geforce 8500 GT and even more so the 8400GS and 8300 GS are in shortly supply, especially when we're talking stock arriving with retailers and etailers. Some of Nvidia's partners are shipping the 8500 GS but not in any really big numbers. The real quantity won't arrive until May as this was the plan all along.
Geforce 8400 GS and 8300 GS are supposed to be OEM cards only and 8500 GT is the only sub €100 card that Nvidia plans to reveal to the market. Don’t forget this chip is DirectX 10 capable and has Shader model 4.0 support.
The cheapest one we could find costs only €80 and it's available as we speak. We are trying to get one for testing, as we are really interested in its performance.
