I would like opinions as what you think of these cards , i already have an 8800 gt, are
both these cards about the same? Does 1 have any advantage over the other.
I just want opinions as i may upgrade.
A 4850 would be marginally faster than your 8800gt, but not world-changing. I would suggest getting a 4870 1gb, GTX260 1gb, or better if you are going to upgrade at all. Opting for one of those better cards might force you to wait depending on your budget.
Cliffs:
4850 == 9800GTX+ / GTX250
9800GTX+ / GTX250 > 8800GT, but not by much
(9800GTX+ is the same thing as a GTX250)
HD4870, GTX260, or better > 8800GT, by wide margin
image quality should be a concern too, http://www.hardforum.com/showthread.php?p=1032904394 http://alienbabeltech.com/main/?p=3188&all=1 i'm thinking of getting rid of my sapphire 4850 and paying the price difference for a 260gtx 216, is the stock reference cooler adequate for this card ? i get as high as 107C on my 4850 running the furmark 1.65 xtreme burning test @ 1280*1024 with the fanspeed set to 75% :S
4850 is about 10-40% faster, depending on settings, and you can raise AA more on it then the 8800gt, and the 4870 1gb is about another 20-40% faster then the 4850, more on higher res and more AA.
