The recent release of the HD 4890 keeps me wondering if I should go for it or not, as you said some reviews say the performance is not that high compared with the 4870, but this is very tempting:

The Price is not much higher than the XFX HD 4870 1GB and with the rebate I might get it for the same price.

The Lifetime warranty is important because like you said probably by 2 years I may want another card, but then I will sell this card and advertise with the lifetime warranty through the manufacturer, so I'm probably gonna stick to XFX...

However I was considering the ASUS Black Knight HD 4870, which have 3 years of warranty,
