An 8800GT and a 8600GT has a lower power consumption compared to ATI HD4890, if I'm not wrong. So maybe you might need 600+? I dunno

He is using huntkey which is at best 70+% efficient only, plus Im sure he definitely OCed it kaw kaw.
My CM 500w can handle 4850CF too.
Don't trust the official rating too much, the manufacturer always exaggerate it, remeber how Intel told us not to OC?

crossfire 4770 runs faster, quieter, more energy saving than 4890. x8/x16 difference maybe in very very high settings at 1920 resolution. other than that, maybe just 5% difference

but not all games support CF/SLI. and if the games not support, it will only run on 1card only.

my recommendation would be just buy single card.

if u already got cf mobo so y not give it a try. its worth it. 4770 gives very good scalling.
im on 4770 cf on a blood iron p45 mobo and it run at x8 x8. afaik the performance between 16x 16x and x8 x8 different is around 2-3fps. so not much different unless on hi reso maybe.
the power consumption is lower a bit then 5850 or 4890.

i got myself a 13k gpu score on vantage both on stock. for crysis on fullhd high setting max fps 45 average 35.

REVIEW see games review. it does give a very good scalling on farcry2 and hawx. other games too it stands out among hi end card.

for me i would suggest u to try it since u already have a cf board and single 4770. get 1 more pcs n rock on

THanx All..I really appreciate all opinions..I would try for any CF or single provided if i found any seller can offer their GC within my budget..thanx again.

try crossfire...me kena poison till now..hd4850cf still the champ for me..haha

hi all, is it possible to CF 4770 with 4850? is it weird? hehe. just want to know.

Yup.Making another card useless.

I think only can crossfire with 48XX with another 48XX.
