What will perform better, a ati hd5750 1gb with gddr5 or a ati Radeon hd6570 1gb with ddr3. I think option two will because of it's higher speed but option one has faster ram.
5750 1 gb gddr5 will be better. it has faster gpu and faster vram.
wow! that's a huge difference, it's like 50% worse then then the hd 5750. I'm basically looking for a budget card to replace my on board graphics so i can play games like dead island and gta iv. I now have the choice between hd6670 ddr3 and hd 5750 gddr5 but the price difference is $50. The hd5750 is looking a lot better tho.
hwcompare only compares theoratical data. benchmark reviews are better than spec comparison.http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/42636-amd-radeon-hd-6670-1gb-hd-6570-512mb-review-6.html
i only linked one game's performance. look through the whole review. 5750 should be okay for gta iv. you'd need a good quad core cpu to run it.
