I just had few questions regarding the SLI connector I'm willing to buy to add a 640GT to my current 250GT graphics card.
Now I did my homework and researched this subject in many different occasions, but it is now that I am the most interested in buying such thing. I am really confused whether I want to buy the 670GTX because of its massive power and multi-view capability, or the 640GT as it offers the multi-view feature that I am seeking most but lacks the graphical power of a 670. So I said why not merge these 2 graphics card because I know the 250GT I currently have is still kicking pretty good for my needs, but not as much as I want it to be.
So I liked to ask the knowledgeable community here and maybe I can get some help.
You see, I read somewhere that an SLI connector can make 1 graphics do all the graphical computing while the other offers the PhysX computing for games, and me, as a graphics designer and a gamer, likes to have as much power in his arsenal... but you know, I hate being broke too. So I wanted to ask specific questions that I couldn't find the answers to while I was Googling SLI connectors. So here we go:
1. I'm no engineer but isn't applying just the PhysX computing on 1 card is a waste of power for any game? I mean as of right now I can play Battlefield 3 on a solid 40FPS with my 250GT, but I'm wondering how exactly will that change for gaming, if that thing I read about PhysX being applied to one card and the graphical computing on the next, what card should I make my primary and why? Is that fact even true or false? Is it really worth it getting 2 cards to power up 1 game, or will the game not take full advantage of both of them and I won't get a significant FPS boost?
2. How will having 2 cards affect my graphics designing. I work in After Effects and 3Ds Max most of my time and I find that CUDA cores help significantly in such field, my question is, will the 2 cards combine their power to render my stuff or again, will there be waste of power because of how the programs work?
3. Is there a real overall significant boost in performance for general graphical computing purposes? If I were to buy a new 670GTX, will that match the power of a 640GT and a 250GT combined with an SLI connector or be greater?
The 2 options remaining at this time is that I could buy the 640GT and SLI connect that ho to the 250GT and have multi-view shiat, or I can just buy the 670GTX and have all of that but maybe with little more power and sell my current PC even though I know I won't get much money from doing that. What options is best for performance and what option is better for my pocket?
