ADDITIONAL COMMENTS: I was thinking about getting the XFX ATI Radeon HD6770 1 GB DDR5 VGA/DVI/HDMI PCI-Express Video Card HD677XZNLC as listed on Amazon.com at the link below, right price, reviewed well on Tom's, and has a nice rebate. Do you think it would be a good upgrade for my system and if so will it work okay with the 475W PSU?
The 475W PSU on the XPS 435T is rated for 16 amps on the PCI-e power connector and 32 amps on the 12v rails.
Thanks a lot for all the posts and advice, I will research everything more tomorrow. From the posts it looks like I should skip the 6770 for sure and go for the 6850 or for a little bit more the 6870. The Dell PSU should be able to handle the 6870 without any power issues right? Thanks again for all the replies, I really appreciate it.
