I have the processor and the motherboard you posted in the first post.
I currently and running with 1 ATI 4870 X2 2Gb graphics card.
But last week i brought another one (saw it cheap in the sales)
When i arrives im going to crossfire it with my current one.
Though i must add i had to buy a new larger Watt PSU to power them both a Coolmaster 1250 watt beast. Expensive but with a little luck it should mean i wont need to upgrade for a while.
I have had Nivida and ATI cards in the past and not had a drama with any of them.
What ever one you go with you rig will fly.
If you can afford it get two cards and crossfire or SLI them and you should not have to upgrade in that deptment for a very long time.
