Hey, I am trying to decide what to do, I want a better video card because online on crysis I get terrible fps on low at 1024 by 756 res (20-40 fps) and if I crank up the gfx to medium/high I get below 20 fps and it can dip down to 10 fps some times under heavy battles.

So, originally I was going to buy a 4870, then I remembered I could crossfire it.

so this is my question....

Can I crossfire a 4830 with a 4850/4870? and if I can, will the 4850/4870 lower its performance to a 4830?

Also, since I am building a new computer I need to know what motherboard to get to do crossfire (under $100 is a MUST) and it be from

Sup dude. very simple.
I just recently bought a Powercolor 4830 from newegg, and I have it on a (ASRock P45XE LGA 775 Intel P45 ATX Intel Motherboard
Tom's hardware 2008 Recommended Buy Award, which was 94.99$ from NewEgg, and its an awsome MOBO.

I am able to play Crysis on a 24" monitor at 1920x1200 on all High Settings with minor clipping. If I turn it on all medium, it never clips.

I am going to get a second videocard to crossfire it with, and i will either get a second 4830, or wait until the new model ATI is making comes out.

Right now you can get a Sapphire 4830 for 74.99 free shipping AR.... GREAT DEAL...

you will need a crossfire cable, I bought 2 from ebay for 12$.

If you have a 4870 and a 4830 in crossfire, the 4870/50 will SLOW DOWN to the 4830's speed.

It really depends on what your time frame is, the new card coming out is going to be between the 4830 and 4850 speed and have DDR5 instead of DDR3. If you can.... I recommend waiting for it.

I don't understand. What card do you have now? If its a 4830, then those frame rates are below par. My 4850 gets ~25 fps on 1440 x 900 all settings Very High. 35-40 fps on All High. So its only logical that the 4830 gives you at least 22-24 fps on all Very High 1024 x 768. Maybe there's a serious bottleneck you're overlooking.

lower resolutions 1024 x 768 will depend more on cpu than vidoe card what size monitor do you have
