Garcian Smith said: Finally, there's a joke among hardware enthusiasts that the 5750 is a good DirectX 10 card (if you know what I mean). It's not powerful enough to run DX11 games at playable framerates. In addition, the 4850/5750 can't really take advantage of more than 512MB RAM, so the extra 512 is useless. The only advantages the 5750 really offers over the 4850 is lower heat/power consumption and slightly better performance, and those really aren't worth paying the extra $40 for unless you're specifically worried about heat/power. |
I've never seen any reviews express that sentiment. The 4850 (and 5750, GTS250) is a good card and has been since launch. It makes most games playable (>30fps) on 1600x1200, which is an above-average resolution for a gamer looking at the Steam survey, reviews, and a few other places. The first DX11 games are really unoptimised and hardware-demanding (even in DX10 mode); the design of DX11 is that it will bring better graphics for similar performance to DX10, once games are designed with it from scratch rather than it being bolted on. Look at the huge drops for DX10 performance when it was first released; now those same cards perform similarly under DX10 and DX9 games.
I've seen people and reviews say the 5670 isn't good enough to do DX11 at playable framerates.
However if the 4850 is $100 and the 5750 is $130 as they are then the 4850 is a better choice.
