How is it going to be bottlenecked? You guys are handicapped. You can pick up a 460 for like $130. I would go with that or the 6850 if you are willing to spend the extra $50.
You will probably need a new power supply regardless of what card you get.
All of you bitching about motherboard compatibility are mentally handicapped. Just about every computer in the last 7 years has come with a PCI-E port. That's like asking if someone has a USB port...
you seem to think, in the first part, that price = compatibility
a new PSU isn't always needed. i didn't need to get one. but maybe i just had a pretty good PSU to start with. :o
not all computers since 2007 have pci-e 2.0 just because that's when it came out, that isn't really very good logic. you're implying they added--
