Message 53878 - Posted: 1 Apr 2012, 2:14:27 UTC - in response to Message 53553.  

currently i have 2 4670's but i am swapping those out with two 4850's so i will be able to run milky way. i chose the 4850's caz the wattage is lower than most of the others(110 watts each) the 4670 wattage is 70 each. i got a good deal.., is there a better card or is the 4850 a good choice? anyone?

The HD4850 is still fine, but getting really old. Sure, it doesn't consume as much power as other cards, but it's also slower. The chip is manufatured in dated 55 nm technology, which is inherently less power efficient than the 5xxx and 6xxx series in 40 nm.

Personly I sold my HD4870 some time ago to a gamer on a budget, as I figured it was not power efficient for 24/7 crunching any more.. for me, at least.

If you want a powerful card solely for this project, get an ATI card. Nvidia artificially cripples double precision computing on their video cards to an insane degree, and they do not perform well here.

i finally settled for an HD5850 1GB DDR5 - seems to be a little more stable.
