Question about crossfiring

[Puddle Jumper]

Hey, my P45 mobo can only do 16x/8x, is it worth it to buy another 4850?

Crossfire 4850's would be a good option for 1900x1200 and the x8 slot on your motherboard won't have much if any affect on performance.

Alright, cool. I thought it would reduce performance by half, because it was half of the speed.

Thanks a lot, Puddle! =D

Edit~

Should I get a 4870? I read there is going to be $50 price drop, and I want in. Shoud I get the 1GB, or 512MB?

2x HD 4850's would perform better than a single 4870.

No, I already have a XFX 4850 512MB. I want another card to crossfire with, because I want better frame rates. Would another 4850, or 4870 512/1024 MB card pair with it better?

Get a 4870 1gb and use it as the master card in the crossfire (in slot one) with the 4850 as slave. It may be better to sell the 4850 and get 2 4870's

There is no master/slave card in CF these days...

I would just sell off the 4850 and buy a 1gb 4870...mine performs very well at 2048x1152 which is just a tad above 1900x1200

Uhh.. sell it?! Can't I just abuse the double life time warranty, and OC it to death, and RMA it?? I might get a 4870. xD How much can I expect to sell it for? It's pretty new for a 4 series card.
