Should I upgrade my HD4870 512MB to a GTX 285? I game at 2048x1536 on my 19" CRT monitor and like to have the AA, AF & eye candy turned up. After reading lots of reviews though, it seems a bit inconclusive. There aren't many reviews that use this resolution and the overall score of a 4870 doesn't seem that far behind and sometimes beats the 285. The 4890 is gonna be released in a couple of days and I guess the 285 will come down in price soon; it's been drifting downwards steadily anyway and the Zotacs are going quite cheap compared to the rest of them. I like to play Fallout 3, Quake Wars, UT3, CoD4, L4D stuff like that on my new E8500 @ 4.2GHz system.
