And since the prices of the GTX 275 and GTX 280 are higher than a 4890, I was just wondering, because if the bandwidth was bigger GDDR3 wouldn't matter.
*EDIT* I found a GTX 280 on ebay for $140 if its a bit better than a 4890 then ill grab that up.
275/280 are very close, and the 4890 is very close to both of them ... pretty much depends on the game and whether it 'favors' ATI or nV architecture. A GTX285 is a bit of an upgrade, but I wouldn't bother replacing a 4890 w/another DX10 card of such similar power.
Now, a 460 1MB card is only slightly faster than a 4890 as well, but at least it does DX11 ... plus it tends to do a noticeably better w/MIN fps, which is nice ... plus it has WAY more OC'ing headroom so it's top-end is going to be quite a bit of an improvement over a 4890. So that's the minimum card I'd consider 'upgrading' to if it was me.
