I currently have an ATI Radeon 4890 and im looking at getting a new video card. These new GTX480s caught my eye but I heard that there are cheaper Radeons out there at the moment that can deliver close to the same power for a significantly cheaper price? So basically I just want to know, what is the best upgrade from a 4890? My budget is around $600
What's your mobo, PSU, and screen resolution?
I agree with welshmousepk, 2 260s will be a killer for ~ $400, but if you're determined to spend the whole $600, go for 2 5850s. If your mobo and PSU can handle them that is!
Yes, if you motherboard is SLI two GTX 460s are the way to go.
If it is crossfire get an HD5850(or two I guess) and OC the hell out of it. Get one that allows for voltage modification for a better OC(usually 1ghz+.) At that point it will give you performance similar to a stock GTX 480 but for $150 less while also using much less power.
