Graphics card chart?

[bloodline76]

I have lost track of the power of the latest graphics cards. What are the top five cards at the moment and how much more powerful than my current one are they?

Thanks

may not be 100% correct
4870x2 crossfire support dependent
4850x2 crossfire support dependent / GTX280 depending on reviewer/fanboy/Resolution
4870/GTX260 216 core depending on reviewer/fanboy
GTX260 original
9800GTX+/4850 depending on reviewer/fanboy


your card most likely fits in near the bottom in non optimised SLi games and around the GTX280 in SLi optimised games

So not many noticable upgrade options worth the while at the moment for me then.
