I have a 4890 currently that i got more then a year ago and I have been itching for an upgrade since the HD5xxx series launched but I stuck it through since I didn't really have any issues gaming. Now i got a 26" monitor and my 4890 isn't doing to well in all the games I play and an upgrade would be nice. I was going to get a 5870, but recently I found out about the gtx 460 and how stellar they perform in SLi so I was wondering for about $450 CAN what would be my best option.
