I would like to crossfire on my GPU for gaming,
here is my desktop spec,
intel core i5-750 2.67
gigabyte p55a-ud3
sapphire hd 5830
kingston 1333dn 8gb
psu 650 watt
If the motherboard has 2 x16 PCI-e slots, sure. Even 2 x8 will work.
But you will probably need a large PSU, pending of what cards want. I don't know how many PCI-e plugs the 5830 has, but if it has 2, then a PSU upgrade will be needed.
