yeah i have 650w psu with an intel core 2 quad Q9400 2.66 ghz.
and i know that gt470>6870>5850, but i need to know whats the best for the money. the 470 and 6870 are the same price, but the 470 i heard is a power hog. also since the 5850 is just below the 470 and 6870, but is way cheaper, that could be a good buy too.
wow so like 2.5w a min? that's like....nothing. both cards idle at less watts then a 9800GT. the ATI 6870 actually uses more power for movie playback. There is no question is uses more watts then either of the ATI cards but lets not make it out like he can't pay his cable bill because of it.
FYI. the cost of going from a GTX 260 to a GTX 480 in terms of increased cost for watts per month, is just enough to purchase one small coffee at DD
All three cards are solid. I've seen the 6870 cheaper than the gtx 470, but it seems to me as though the 5850 is the best bang for your buck in this case. In a few cases it outperforms the gtx 470, tohugh it's consistently beaten by the 6870. All three cards are great--but for that price and the power consumption you can't beat that 5850.
Do you plan to crossfire? The new 6k series usually scales better under crossfire, which actually makes them equal to or better than the old series. Even if you don't, drivers haven't totally matured for these cards yet, although they are similar to the old gen, they aren't exactly the same(especially since 1120 shaders can now beat 1440 shaders, 6870vs5850).
The GTX 470 generally equals or beats the 6870 though(except when two cards are present), so it would also be a good deal.
When tessellation becomes more popular the GTX 470 will also scale better under higher tessellation factors, this will make the GTX 470 a better choice later down the road if it can still play games with its better tessellation scaling anyway .
