Two graphics cards. Not for gaming.

[jimzepellin]

I'd just like to state that this is not so I can run games. I just thought I'd mention that because I've found similar questions asked on the web and all the answer all seem to descend into a conversation about gaming options and totally ignoring the original question.
What I'm trying to find out is if there is any performance hit using two different graphics cards.
I've just got a new graphics card and I have an HD4000 on the processor. I've got my main monitor wired up to the new graphics and I thought I'd try plugging in an old monitor I have into the HD4000 The old monitor only has VGA connectors and the new card doesn't.
Plugged in, working fine. I know you can use two cards to speed up your gaming but this is not what I'm talking about. The fact that these are two different graphics cards from two different manufacturers will there be any performance issues. I only installed the new graphics card today so I've not had time to see if there is any kind of problem. I just thought I'd pick folks brain here to see if anyone had any experience with this kind of thing.
It all seems to be working fine at the moment and if there isn't any hit in performance then I can use the old monitor until I get another to match my main monitor.

Thanks for any help.

I think you have answered your own question.

Wait wut?
Youve got signal from both GPU and onboard?
I thought once you put the GPU in, you have to disable onboard graphics?

Or have I read this wrong?

No you don't. I run SLI 680's and still have the onboard enabled. If problems arise, it is better to turn the onboard off.

The question seems to be redundant for now. Both cards were working fine all day yesterday. Over night it looks like the gremlins were at work and when I woke up this morning I can't get any signal from the HD4000. The drivers don't seem to be loading. I'll have to have a look into this but I've just got new graphics and I want to play with that, so I'll leave it until I get bored playing.

I think you have answered your own question.

Why, how where?
The basic question is can I expect any performance hit with my setup. Even if it's a small amount that I may not notice. I'm just checking to see if anyone else has had the same experience and see if they have any advice. I can do without the extra monitor until I get enough cash for another monitor but having the extra monitor until then is handy.

The fact that there's been a problem may mean it may not be worth the bother. I had a hell of a time installing my new power supply yesterday. It took three hours and a lot of grinding and wrenching of metalwork. I'm in no mood for messing about so I'm going to chill as it's not too important.

Thanks for the replies.

There is always at least a small CPU/Mem performance hit from using integrated graphics, but none apart from that.

Thanks. I never actually thought of that. I was thinking more about the graphic cards not playing together but that makes perfect sense. I think I'll stick with the one monitor just now, it's 24" so plenty of room. I only wanted the other monitor for watching and reading tutorials while I work on the other monitor. I think I'll just save up and get something that's going to give me less problems.
So I just need a little more help. Blank checks and any spare cash. No coins thanks, wears holes in my pockets.
