Hi,
I have a Dell XPS 8700 with a HD 7570 1gb graphics card and a 460 Watt OEM PSU
I found a Black Friday sale for the R9 290 and I want to upgrade.
I need help in finding a psu (750W) that will support the 290 and fit in my case, and if the 290 will fit well into the case.
Also I found that some people were having to update there Dell Bios to support there gtx's, do I need to change my bios or update it if I'm getting a r9 290?
Thanks in advance.
