Nvidia's sales promised a US$199 card that ends up at US$229.99.
The XFX 8800 GT 256MB card ends up at $229.99 before mail-in rebate and, after you send a letter, XFX will give you back your $10. This is an unnecessary complication that is not present in Europe, but the company apparently hopes that many will be too lazy to ask for their $10 back, and we am sure that strategy works quite well.
XFX is still alone in the US with the 8800 GT 256MB cards and if you find one in Europe they tend to get much more expensive.
The American card is here, while the cheapest one in Germany sells for € 198.90, including 19 percent of German Mehrwertsteuer, or VAT. You can find it here.
