I was considering replacing my sapphire 5770 after my last thread speaking of it's odd behavior. Reinstalled drivers one more time, maybe it'll work, maybe it won't. I was considering this http://www.newegg.co...Item=14-150-548 due to decent price, 2 free games, and you can't beat xfx's warranties. My only issue before I buy it is, I don't know if my psu will handle it. I will list my tower hardware and maybe that will make this easier to determine. 600w Rosewill Performance PSU http://www.newegg.co...pk=rp600v2-s-sl phenom II x4 2.8ghz 95w http://www.newegg.co...N82E16819103656 (b93 which is the business edition, no different specs) 8gb crucial sport 1600 ddr3 http://www.newegg.co...N82E16820148544 biostar ta970xe http://www.newegg.co...348&Tpk=ta970xe hyper 212 evo http://www.newegg.co...N82E16835103099 ocz agility 4 128gb ssd http://www.newegg.co...N82E16820227807 500gb black caviar hdd http://www.newegg.co...N82E16822136795 I have probably 3 performance fans, and 3 generic fans in the case. Just removed two raptor drives in raid so those are irrelevant. I do occasionally run externals on the system too. Obviously additional hdds in the future is possible as I do have a few more 500gb/1tb drives lying around the house This is the card I'm currently running sapphire 5770 1gb ddr5 http://www.newegg.co...N82E16814102858 looking at this: http://www.newegg.co...Item=14-150-548 -now it looks as though the required power supply for the 6950 compared to the 5770 is only a 50w difference between the two, but I have considered my current issues with driver crashes could be due to my power supply's inability to keep up (although unlikely). What do you guys think? Would this be suffice for what I'm looking to buy, or would I have to upgrade the psu as well? Thanks for the help.
