Upgrading Inspiron 530s


May 28, 2011
Looking to upgrade my 530s, which I've discovered is a major headache. At least as far as finding parts that fit. I have 3 things.
1. Upgrading the graphics card. I put a Radeon 4650 in, which has been great. Unfortunately, Witcher 2 is not cooperating. I was looking at the Radeon 4850 or 5770. But...
2. The power supply. I've found one on eBay that's 320w, but I'm worried it won't be enough. I also found one on eCrater that says it's 400w. Do you think it's legit? Or would the 320 be fine? Maybe a different graphics card you'd recommend? http://www.ecrater.com/p/8716434/4 [...] ell-power#

Thanks for any help. Much appreciated.

UPDATE: I originally posted this under Power Supply forums where a user suggested trying here. He also recommended the Radeon 5770.
