HD 4890 Performance will be between GTX280 and GTX285
not GTX 260 (216 SP) Because that what HD 4870 1GB do
RV790 is not a faster RV770 http://www.fudzilla.com/index.php?option=com_content&ta...
"" It looks like this new chip will beat the GTX 260, and it could even get close to GTX285, but at a much more affordable price. ""
From someone who actually owns a dual GPU card, and yes I actually own 2 in crossfireX I believe people are grossly over-thinking the problems they have. Drivers have never really been a problem for me, sure there were some bugs but I took care of most of them. The only real problem I've ever had was in Fallout 3 with some memory leaks causing terrible performance and crashes until a patch came out. I would easily buy another dual GPU card over a single card as long as the dual GPU card was atleast a bit faster.
but I'm not sad for buying HD4830 even at 100$ because ..card Like
GF 8800GTX or GF 9800GT was just hard dream for me one year ago ..
now it's come true with HD4830
(and from six months ago i was just close to buy GF 8600GT for the same Price)
after that i bought HD 4650 for 70$ (i will sell it soon with all my system)
now i will have new system soon with AMD PhII 710 X3 and HD 4830
I own a GX2, and can't use drivers past 181.20 (or any prior 180 driver) due to constant total lockups (tested on clean PC, its the driver). Throw in the odd performance in some games (HAWKS for instance, has a 285 beating a 295 by almost 20 frames according to GURU3d), and I'll never buy a X2/GX2 card again.
