Msi 890gxm-g65 crossfire with IGP?

[redstarjedi]

Hello,

I am the proud new owner of a msi 890gxm-g65 mobo. I currently have an old 9800gt 512mb.

I have read that since this is a crossfire enabled mobo, i can link up the onboard ati 4290 igp to another ati video card. I am very intrigued by this possibility!

However, i do have the following questions about what restrictions apply:

Is this a particular model of an ATI card that i am limited to?

For example if i were to purchase a single 5770 or 5850 could i link that up to the onboard igp?

Or am i limited to only installing another 4290 card? If so, could i then reasonably install two 4290's and link it up with the onboard?

Thanks in advance

-Tony

P.S. any comments about the performance with 3x4290's versus a single 5850 would be appreciated.

Well, I can't honestly tell you much about Hybrid CFX, but I think it would require a second/third Radeon HD 42xx card. I'm not sure, though, as I've never seen an actual discreet 42xx card for sale.
It really wouldn't matter, though, as a single 5850 would probably smoke three 4290s. I'd even take a 5830 over them.

If one 4290 can only pull 16fps in STALKER: Call of Pripyat at 1280x720 on low detail with no AA, then I'd say three of them wouldn't be much better. You'll have to have someone else confirm whether or not you can put a GPU from a different series with the integrated graphics, though, as I'm really not sure. I'd go ahead and get a 5830, 5850, or whatever it is you wanted...

don't even worry about any kinda of crossfire with that iGP, if it's even possible, if anything if you did crossfire any moderate powerful card to the IGP you would most likely lose fps over the one card by itself
