I wanted to get the Radeon HD 6670 card since my last card died on me. Currently using the integrated graphics on my mobo, the HD 3200 series (Which has been painful...). As I was browsing, I noticed that the 6670 had both GDDR3 and GDDR5. The difference was that the GDDR5 has a 25 dollar difference over the GDDR3. Is it worth it? I mostly use my computer for casual gaming. I was wondering if the GDDR5 will deliver a noticeably better performance/fps rate and make use of the 25 dollar difference.
Here are the links:
With resolutions and graphics options at the edge of your graphics cards ability it will make a noticeable difference, between DDR3 and GDDR5. However the few comparisons I had seen were using roughly half the DDR5 with the same set of processors. With both of these having a Gig of ram I would hazard a significant edge of around 5 to 10 frames per second to the GDDR5. Weather or not that is noticeable to you and worth having for $25 with the games you play and your system is up to you. I would be willing to bet that the GDDR5 board will age better over the next few generations of games though.
Oh side note if you are currently playing older games or at lower resolutions going from 55 frames to 60 isn't really noticeable for most people. Going from 20 to 25 really is, so keep in mind the frame rates of your game at your settings.
There are also 6750 gddr3 going for the same price as the card geekapproved listed (Even one that's $10 cheaper). I'm not sure how exactly they compare performance-wise (since I think the 6750 benches are done with gddr5 models) but the 6750 is not low-profile and has slightly higher PSU requirements. I'm not sure if low-profile and lower power is a requirement in this situation or not.
I am curious though performance-wise how the 6750ddr3 compares to the 6670ddr5 since the regular 6750ddr5 so handily dominates the 6670ddr5.
