I am looking to upgrade my video card. I am drawing a lot in 3D using autocad. I am going to start drawing in Plant 3D and also I do some inventor. My issue is that when I render my models in Autocad it lags big time. It's to the point that I am scared to rotate my model because it may crash. I am running a Dell 8300, Intel Core i7-2600 CPU @ 3.4 GHz (4 cores, 8 logical processors), 64 Bit windows 7 w/12 GB Ram,. I think the culprit is the video card, which is a AMD Radeon HD 6700. I have checked specs and not sure what to do. I was thinking off upgrading to the Nvidia Quadro K2000 which is recommended here (http://www.pugetsystems.com/labs/articles/AutoDesk-Auto...) and it's certified by autocad. According to this other site though it has the AMD Radeon pretty high on the benchmarks, http://www.videocardbenchmark.net/high_end_gpus.html. Of course you cant go just off benchmarks because precision is more important in what we do than speed.
ive been researching to do the same type of programs. Ive come across the nvidia quadro series. The newer K series. K600, K2000, K2000D, K4000 and K5000. Im looking at the K2000 at the price of about 450$. the k600 from what i read is a good entry level card for about 160$ i think.
