Will HD4870 make much of a difference at 1680x1050?

It'll make Crysis actually playable with all settings on "Very High" (so long as you have a fast CPU as well).

If you don't acually give two ***** about Crysis, then save your cash and go for the HD4850.

Cool, I was considering using some of the money to get a better mobo with two PCIE 2.0 slots so I can crossifire in a few months.

Crossfire HD 4870 on my system with a Q9300 at stock 2.5GHz with 4GB DDR3 RAM on a sysem with 2 PCI Express x16 2.0 lanes on Crysis on Very High is usually above 20fps (about 23ish fps), in some spots it can jump up to 28-30fps and in even other spots 35fps. In very intense action it can drop down to about 15-18fps. They really need to optimize that game for Crossfire and ATI's shaders.Marfoo

Yeah. I think Crysis is even more cruel to Crossfire than a single GPU setup. It really sucks. But then again, Crysis is overrated. Sure, it's beautiful but it's not "out of this world." I've been playing Crysis for the visual eye candy, lol. Not so much the gameplay or story.

Crysis isnt so kind on Crossfire setups. You should know.

Faster CPU clock alone may be the culprit, since Crysis doesn't scale well with Crossfire. I could be having a problem though, I'll have to look into it.

yeah marloo crysis don't scale well with crossfire. really not well. cause like poeple said 2x4870 or R700 defeat 3-way sli 280GTX also for less money. on 1920x1200
because R700 alone perform better then 280GTX SLI in most of game so .marcthpro

Yeah I took a look into it, one HD 4870 is actually faster in Crysis at lower resolutions, and the difference between one card and Crossfire at 1920x1200 was only a few frames. They really need to tighten up the Crossfire performance in Crysis, all other games scale well though. Also this is demo performance, not v1.2, so that may also affect my performance.

Well, HD4870x2 promises to scale A LOT better than Crossfire and it also promises to be microstutter-free. At this point, I'm definitely going to switch over to HD4870x2. It's the best bang for your buck for what it can do. We're talking high resolution, no microstuttering, high framerate for a single GPU slot setup, and unbeatable price compared to GTX280 SLi or 3-way SLi. I made up my mind. ;)

Off-topic: Marc, I'm at 4.0ghz now. :)

4850 same as 260GTx performaneces 260gtx > 9800GTX the Equation ain't im right ? marcthpro

No. HD4850 ~ 9800GTX+ (About equal to, give or take). GTX 260 > 9800GTX+/HD4850.

oh so 4850 is like damm weak is like 9800GTX around and 4870 is like 280gTX i see. cause R700 > 280GTX sli ?

HD4850 = 9800GTX+ < GTX 260 < HD4870 < GTX 280 < HD4870X2

The 4870 suffers from near unacceptable power consumption though, IMO.

you mean
HD4850 ---- 9800GTX+ --- GTx 260 --- HD4870 --- GTx 280 --- GTX 280 sli ---- 4870x2(R700) -- 3-way 280gTX -- R700X2

one quesiton if 4870x2 ? is that strong why it only outperofmr 280GTX SLI only in. hmm Grid & Age of conan
and lack of fps in oblivion ?
