I may have sold my GTX 260 Core 216 for a 4890 ( I like 8xMSAA and it kills Nvidia cards ) But I know one thing.... When Fermi finally does see the light of day these forums are going to erupt!!

I think it will be slightly faster then a 5870 and if the rumors are true, it'll trade blows with the 5890

After all the waiting and talk from Nvidia it needs to be faster although things never do live up to the hype
