Vista - Dual branded cards under different O/S's

Hello people,

Well, i am going to start thinking about going for another upgrade,
Core i7 940 with 6GB 1600mhz ram with full water cooling apart from the one card. But with this upgrade i want to have full True HD and of course only ATI offer that.

Now at the mo i am running the 8800 ultra's SLI and want to go up to the GTX 280 or 285, but i want to use an ATI for movies and TV. Now i am fully aware that you can't mix brands of GFX cards under one OS, but i am running vista and 7 over a dual boot.

Now my question is, can i have the ATI run for only vista, so that would become my entertainment OS and have the SLI setup run only under 7.

Is this possible or am i just being to daring for a let-down?

Help is always appreciated!!

I dont think thats possible and even if it was why would anybody want to do that

Buy 2 of the ATI radeon HD4890 and link them in crossfire or wait for the HD4890x2 to be released and you will have no problems. Just a quick tip as well dont watercool your graphics card, instead watercool the NB on the motherboard. A decent site to get watercooling gear from is http://www.watercoolinguk.co.uk/catalog/

Windows 7 can let you have different DX10 graphic cards (ATI and Nvidia for example) with multiple drivers on.

Though what do you mean by full HD? A few of the GT200 cards have HDMI ports on.

That was a better answer than i expected. thanks, tip of the scales for you.

I mean true HD 1080p, the same signal as Sky for instance. Nah i want to be able to play games with no problems. like crysis and GTA IV (and yes i know its not co0mpatible with SLI).

But thanks for the answer above though
