I have an issue with the PSU. FSP Group makes good PSU's, but you only have 23A on the combined 12v rails. It is also only >70% efficient, which means it runs hotter the closer to it's load limit. It might work on the 5770, but your cutting things close. I'd consider spending $15 more (initially) and get the Corsair 400cx PSU. It's $55 shipped - $15 MIRc = $40. You get 30A on the 12v rail and it's >80% efficient too.
