My cards are due in Monday. 2 HIS HD3870 from NCIX. They are sequential barcodes and the serial numbers are 4 apart. Thought it would be a good opportunity to see how closely matched they were. Anyone have suggestions for what battery of benchmarks/tests I should put them though to determine how closely they perform? Plus, if anyone has links to all the Hotfixes and whatnot I need to get Crossfire going in XP and Vista it would be much appreciated. As info, my system is: E6600 @ 3.7GHz 975x chipset=8 x 8 PCI-e Mushkin XP2-6400 @ 1024MHz Let me know what you want to see run and I'll try to accomodate. Besides, I've got to get them tested quickly as my wife is requiring them to be wrapped and under the tree for Christmas (as they are a gift from my kids)!
