No.
HD 4870X2 has exactly same memory as GTX 280.
the X2 has: 2x 1024MB (and uses 1024mb, because every gpu renders the same frame in their own memory twice.. i wont explain now, you can read everything above)
to the 4850X2 - a HD 4850X2 2x 1024MB doesnt exist as far as i know, maybe it does, then it will outperform the normal GTX 260 and HD 4870 for sure. But still it has just 1024MB.
But hey, 500W is damn much. Since PowerPlay 2.0 doesnt work on 4850 and 4870 (on the X2 cards it works), they wont undervoltage in idle so it still needs full power.
500W is damn expensive. For example, germany. (i know its hardcore expensive here). 1kWh (=1000 Watt) costs 20 euro-cents.
So, leaving online your computer 2 hours, costs 20 cent for you. here. Now think about leaving the PC online 8 hours per day the whole year. I know that your PC wont kill 500W every hour, but 350 for sure with two 4850s. still damn much, if you live in germany where this is expensive.
To the micro stutter thing - some people do not notice them. Somehow, it depends on your eyes. For some people it just isnt smooth, while other people would love to play so. So its not just the game if you notice the micro stutter,the sensibility of your eyes play a role too. For myself, i notice them in a lot of games.
Well, with CFX and SLI not working - there are possibilities.
You can make a lot of games (not all) "SLI compatible" with the tool "nHancer", .exe-renaming and other stuff. I dont know if nHancer works with ATI cards too, but i doubt it.
But the good thing is: every GTX 260, HD 4870 or GTX 280 have anough power for all games. You dont need dual-gpu cards if you do not play on ultra high resolutions like 2560x1900 with 4x Anti Aliasing.
