Member Milo Posted May 31, 2012 Member Report Share Posted May 31, 2012 Hi, My wife was asking what I wanted, and I had been looking at video cards. I currently have a Radeon HD 5770, and seeing that 3d-coat has CUDA support, I started looking at some NVidia cards. The 'latest' gen 6xx series it out, however they have a 570 with 1.2 gigs of ram and a refurbished with 2.5 gigs. Asside from the nervousness of getting a referbished card, will the extra ram really help? I might someday get into GPU based rendering like Lux or one of the others. There is support for any of the later NVidea cards due to CUDA vs having to have a specific card (an assumtion on my part). I would appreciate the thoughts as I am sure the card will go soon.

Reputable Contributor digman Posted June 1, 2012 Reputable Contributor Report Share Posted June 1, 2012 If you are looking to the future for GPU rendering, you will want to consider how many cuda cores the card has, plus in Blender if you use cuda for the Cycles renderer, then the textures are stored on the video card ram... so the more ram helps there too. I am not sure about Lux... 570--- 480 cuda cores 680----1,536 " " 690--- over 3,000 (2 gpus on one card) I will be upgrading as well, so these are the same things I'm considering, Cuda cores and amount of ram... Of course all decisions are also based upon how much can we break the piggy bank for... Quote Link to comment Share on other sites More sharing options...
Member Milo Posted June 1, 2012 Author Member Report Share Posted June 1, 2012 Good point on the Cuda Cores.. the 680 gets up higher in price and requires at least all the cards I saw PCI 3.0 which means a whole system upgrade while mine is older the funds aren't there for that. But it sounds like from waht I have been reading in other threads that the 570 works and its a question of the extra ram or not. I am leaning towards the extra ram. Eventually a new system and higher card but thats going to be the future. Quote Link to comment Share on other sites More sharing options...
Member randomguy_j Posted June 1, 2012 Member Report Share Posted June 1, 2012 If I remember correctly PCI 3 is backwards compatible with 2.0. It will just run at a slower bus speed. So what you could do is go with the faster card so that when you have a faster mobo you wont need to change cards for an upgrade. Quote Link to comment Share on other sites More sharing options...
Member Milo Posted June 1, 2012 Author Member Report Share Posted June 1, 2012 OooOO thank you for that information. That is going to make me rethink and look at the 6xx cards! Quote Link to comment Share on other sites More sharing options...
