I just bought a MSI 790fx which has 4 pci express (2 16x 2 8x) slots. I have a MSI ddr3 1 gb 4670 card now. My friend has a DDR2 XFX 1 gb 4670 card I could get for free. His windows index rating is 5.8 and mine is 6.8. Would crossfiring the 2 cards be worth it because of the offset of running at DDR2 because of the XFX video card? For the long run which setup would be best 4 4670s (could fit because of size) 2 5750s? or 2 4870s?

I have not seen any reviews on the advantages and disadvantages of having a lot of small cards, but I think you would be better off in the long run with two large ones - whatever the budget can reasonable afford given your needs.
What size monitors are you trying to drive?
If you need the power, I would be more inclined to go with 2 5770s - if a budget issue just get one now and add the other later when you can. Depending on your monitior, you might find teh 5770 satisfies you for awhile by itself anyway.
I have a samsung t260 which doesn't have a great response time (5ms) I ordered a HIS 5770 for 153$ to the door from newegg. I seen where the 4870 outperforms it a little but decide to trade it for the direct x 11 and power consumption advantage. I've never dealt with HIS but it received 4 eggs so I hope I'm ok and the drivers for windows 7 ultimate and the card don't conflict. Thanks for your help!
