    i have a few more questions about the 4870 performance , when i was having stuttering problems with my sapphire 4870 512 which i purchased last august . it has taken me 3 moths to get the local retailer to replace it , but the stutter @1680x1050 is still present no matter the driver or res i use . so i put my old gecube 3870 gddr3 oc ltd edition back in and purchased a second matching card from ebay , then reinstalled driver 9.6 and no stutter at all in any game i play . i must admit the fps is a little lower but as smooth as silk even in crysis warhead , now i always thought the 4870 was more than twice the performance than my old 3870's in crossfire (pictured below) . i even overclocked the 4870 to 800/1000 (4000) , but my old 3870 has gddr3 and although overclocked by gecube i clocked it to 870/1000 (stock 850/960) . should not the 4870 be better than 2 3870's in crossfire or did i get it wrong ?

    thinking of doing the same as i can get a new 3870x2 cheapish , i think i will just sell the 4870 tbh . i did manage to break 9000 in vantage with my setup today at clock = 800/1000 ,but at stock i get around 8400/8500ish with the 4870 @stock

    I only ran Vantage on the x2 gpu. I haven't ran Vantage sense, It's a bench for Nvidia with its Physics x so i haven't tried it sense adding the single gpu for the tri-fire... x2 only scored a shade below 10k :wtf:

    2 3870's are much better rather than a single 4870...

    why though they only have 320 cores for the 3870 and 800 for the 4870 , and 2 3870's in crossfire means 640 . how does it work though erm never mind lol (my heads hurts ;) ) , just going to stick with what i have for the time being or may be get the phenom II 940 and sell the 720BE

    another question : whats the best heatsink paste for a gfx card ? , i have also notice on the 3870 i got from ebay is the cooler seems a little loose . i have tightened it as much as i dare but it is still a little loose (well i can move it with very little effort)
