I want answers based on the card's and their performance. Not just because it's ATI or Nvidia. I'm an Nvidia guy myself, but Im building a comp. for someone else and they have no preference... So which will be the better card of the two for gaming.
However, i really wouldnt pick either of them right now, for the price of the GTX275 you can get a 5850 which will be stronger and use less power http://www.newegg.com/Product/Product.aspx?Item=N82E168...
and in a couple hours we may find out if the 5770 performs similarly to a 4890 for less, but we will see, its going to be a fun month for graphics, the lower end ones will be coming out from now on but a 5770 may end up fitting the bill perfectly.
Im going to be using a i7 860cpu.... and to start with and possibly keep for a year or so, it'll stay a single card config... but Im going to keep my options open to Xfire if I go with a ATI card, just like I would with SLI
The i7 860 is more then enough for gaming esp if you SLI/Crossfire.
He's suggesting that you consider a 5850 for the gpu; taken into account that it's just a hair off of what you were going to spend on your gpu and it a ways more capable and compatible with future games. I would also suggest that.
a single card is the power of a HD 4870.
Now if you dual, you reach (crysis) and even rape a single HD5850 but the advantage is not noticable. the card is 150 while HD5850 is 250. Your really better going with a single HD5850 solution.
Q1 2010, nvidia will release "FailMI" and hopefully wel see a good price drop, good enough to let you get another HD5850 and get the most out of your computer. or you can do this same tactic with a HD5770 if your low on money.
I myself am in a special position because Im getting the HD5770 for free > so ima get another one myself and get HD5850 like performance for (hold your breath) 180$ CAD. > Im eviiiil.
It's up to you, if you can survive with a HD4870 like GPU until XMAS, then I say go for it!!!! > if you want neat performance and you have a few bucks saved, go HD5850 FTW.
Ah, PhysX is a joke, really. All it is .. just floating papers and flags look more real when waving in the wind .. crap like that. It's a useless technology. Probably won't even exist for too much longer IMHO.
