Note that they have exactly the same price in my country(Turkey), 215 USD.
My screen is 19" and 1440x900.May be i'll move on a larger screen much later.
Btw, my mainboard is Asus P5W DH Deluxe, which supports crossfire.I'm not leaning towards crossfire, yet.I don't know if i should consider it in the future.Because, probably a new gpu will come out a year later and beat two of 4870s easily...
Why does nobody list the compatibility with SLI and Crossfire? If your motherboard supports one but not the other, it will be a cheaper upgrade down the line if you get that company (SLI-nVidia, Crossfire-AMD). However, a 260 will beat a 4870 in most benchmarks and I have not heard anything about the brand Sparkle, but Sapphire is notorious for having bad support.
