VR Zone claims NVIDIA has delayed the GeForce 9800 GTX launch from March 25th to April 1st.
GeForce 9800 GTX will be priced at US$349. On a side note, the industry is speculating that Nvidia might be forced to lower the price of the newly launched GeForce 9800 GX2 soon to better compete against Radeon HD 3870 X2 card which has a better price/performance ratio. Currently, 9800 GX2 is priced at ~US$599 while 3870 X2 is priced at ~US$410, nearly $200 difference. With that amount, you can get another HD 3870 card, set up a Hybrid Crossfire (3870X2+3870) and has a potential to achieve better performance than the GX2.
