I am building a new i7 970 system with 2 monitors and agonizing over which video card to get.
I can get 2 EVGA GTX 460s for about the same price as 1 EVGA GTX 570. They both are super clocked and have about the same spec.
Except: cores - 336 vs 480. Memory - 1GB vs 1280 MB. Memory interface - 256 vs 320 bit.
I have read some threads here and as one should expect, the results say ‘your milage may vary’. (Currently have a 9800 GX2 which has CUDA.)
I have asked a question on the NVIDIA forum but have received mixed response as well. Part of the problem is, I think, that they are gamers and I am not. Another part is that the modern video cards are designed more in the direction of gaming while video editing doesn’t use the modeling, texturing, etc. that games do. Video editing and display need encode/decode processing. (I see that some new Intel CPUs are out which contain video encode/decode processing in the chip. However, as Vegas / DVD Architect doesn’t use that yet and the higher level CPUs are not yet available I am ignoring them at this time. May be in 1 or 2 years.)
As I don’t understand how CUDA works or how Vegas uses it I have the following questions that I hope someone can answer or at least confuse me at a higher level.
Will Vegas use the processing in 2 cards if they are not connected (SLI bridge)?
Will Vegas use the processing in 2 cards if they are SLI bridged - that is, does Vegas use SLI?
As CUDA is a method to use multiple processors, I would guess that the more the better?
Does Vegas / DVD Architect use any other feature (PhysX etc.) for display or rendering/encoding? (I doubt it, but then “I know nothing...nothing”.
Any thoughts on which card would be best with Vegas?
Thanks for any comments.
