Want to run crysis very high 2560x1600 please help

Hey guys I built my first computer back in october of 2009. I have an i7 clocked at 3.4 and a single 5870. I also play on a dell 30 inch 2560x1600. My mother board is the EVGA 3 way sli. My psu is a corsair 850. (i realize i might have to upgrade to 1000)

I know my single 5870 is not quite good enough to get the job done at 2560x1600. I looked at some benchmarks for crossfire 5870's and they seems to average around 30 fps. I really would like to get more than 30 fps. I am looking for a better graphics card set up to get a nice solid FPS (maybe 40's-50's) with crysis at very high 2560x1600..... what do you guys suggest?

Should I go for a tri fire 5870? The only crysis benchmark I could find using three 5870's @ 2560x1600 only had it at 35fps. Which was 5 more fps from two 5870's. I am sorry, but if I am going to spend 400 dollars on a 3rd 5870 I need to get more than 5 fps lol.

Or should I say screw it and just get two 5970's? Only thing with that is I would be wasting my single 5870 that I already have (

What I wanna know is what kinda fps could I expect to get with crysis @ very high with a 2560x1600 reso with something like a tri 5870 or crossfire 5970 set up? I dont know why, but its like pulling teeth trying to find benchmarks with this kind of set up using 2560x1600. I am hoping you guys can help. Thanks

I don't think any current card or config can run Crysis that high. As you see, the benefits of going from 2 to 3 cards is much less than from 1 to 2, and going from 3 to 4 will be even less. If dual 5870's can't do it, then you will probably just have to hope the new NVidia card coming out in 3-6 months is significantly faster. Crysis is still a very demanding game.

..... if 3 Crossfired 5870's get 35fps, a 5970 will get like 15....

2 Crossfired 5970s will net you probably about the same as three 5870's.

Only way to get higher would be to get 4 5870's and 4-way Crossfire them. That would be expensive though

As I said, if you're gonna go that far, screw it, get four 5870's, crossfire them, OC to hell and back, and get some peltier liquid cooling going on those biatches.

Then you might get 45-50fps at that res..... but you'll also use enough power for a small town and be able to melt steel by setting it on your case.....

adding a 5970 wouldn't be the same as three 5870s, it wouldn't be a lot slower... but it would be slower nonetheless...

Hmmm maybe I should just wait for Nvidia's cards. How do you know these new furry cards will come out in 3-6 months. I dont wanna wait long lol

if i am not frong thay will be out in march. Am i wrong?

Yeah, i guess you are right, it is only 2-5 months now (keep forgetting January is almost over.

Our society on earth as a whole does not work like that. I work hard for my money. I earned it.

Anyway what is up with this furry from Nvidia? Is this suppose to blow the doors off ATI?

We don't know if Crysis will favor Fermi at all. It's a totally new architecture, and anything could happen.

Just because you flip a coin and it lands on heads twice in a row, doesn't mean it will land on heads a 3rd time. And while they had changed their architecture before, Fermi is radically different than previous architectures. It's really designed for GPGPU computing, but modified to be able to run gaming 3D as well.

I'm not saying it won't perform well, but by the charts I've seen, I don't quite see the Nvidia dominance you are talking about at the present moment.

Do you have any trouble with the fight on the Carrier flight deck? For whatever reason, even though the rest of the levels run flawlessly, that one runs poorly and has crashed three or four times for me.

A matter of fact, I did have some trouble. It appeared to be a memory leak, as everything would run smooth, and then slowly slowed down and crashed a couple on the flight deck only.

I thought it was due to having aero on, or the Ultra mod I had installed.

That is exactly what I experienced. I have heard that turning down to medium may help. I have the 9.12 hotfix drivers, Win7 (though I could try turning off Aero), and the latest Crysis patch (which does fix some memory leaks, but I guess not for me).

I know Aero helped earlier in the game. There was a couple times that the game slowed down on me and win 7 gave me a warning that I was running out of memory. I turned off Aero and the problem went away. I forgot to turn off aero before the last session I was going through the carrier, I should go back to a saved game and see if I have problems while Aero is off.

With an overclock on the core the 5970 will perform like 2 5870. Even though the 5870 have their own dedicated buses that doesn't mean they are better, because the 5970 is not limited by it's single bus, only by the core frequencies.

Seeing that the specifications are the same and only the GPU speed differs there is no other difference. The bandwidth still doesn't saturate the PCIex 2.0 so that is not an issue here. And related to the cooling. Some people might disagree here. Ask jay2tall about X-fire setups and cooling 2 cards. Always the top card will have higher temps than the bottom one which might generate in not so well ventilated cases problems.

Did you look at that benchmark? It does show fairly average comparison difference of the ATI and Nvidia cards. The cards that normal beat the next is the same in that benchmark and by about the same as normal.

You could possibly have something poorly configured in your system. Generally having over 45 fps at all times is considered quite comfortable. In my system, with 2x 5870's and an i7 920 at 3.5 ghz (what I've seen in benchmarks show that most games will be GPU at this speed still), the FPS almost never drop below 45 with a couple rare exceptions that are mostly non fighting spots.

If you feel the need for over 60 FPS, then ya, it won't, but neither will the 285's, as that benchmark shows the 2x 5870's handily out perform the 285's.

don't be a hero kid. you'll have more luck dividing by zero
