Sapphire* ATI HD 5670 1Gb DDR3 vs *HD 6570 1Gb DDR3 vs *HD 6670 1Gb


Jan 20, 2013
Hello! I'm planning on buying a sub 100$ gfx card for my old Core2Duo E7300 2.66Ghz, 4Gb RAM, 1280x720 mon. reso. PC which my younger brother is going to use to play games. He's sort of a casual performance gamer which means he's in it for the story and game play rather than mind blowing visuals, tesselation, crisp textures etc. and doesn't mind dialing back the settings to resolutions as low as 1024x768 as long as the fps is smooth enough for him to play. Anyway I was planning to buy a really good 200$ gfx card but our mum beat me down to sub 100$, other than that I also realized the PC's PSU is probably a generic-brand 450W one. So I narrowed down the search to the HD 5670, 6570, 6670 all Sapphire 1Gb DDR3 (DDR5 wasn't available) which I guess would work on that rig. But I want to be sure I'm making the right choice. So my questions are:-

Which of these cards gives the best price/performance?
Will any of these run on the PC's 450W PSU without problems?
What fps can one expect on these for games from 2011-2012 played @ 1280x720 with medium to high settings?

Thanks for your help!
