It's not free. That exact card without any combo costs $269 after mail-in rebate. That card costs $359. So basically, he's paying $90 for a $129 motherboard. With that in mind, I'd definetly get the $269 7800GT and a MSI K8N Neo4-F or a DFI LanParty. Here's a link to the video card for your convenience:
