Looking for some help in buying a card

post #1 of 16
Thread Starter 
I currently have a GTX480, I'm looking for another GPU to run along side it, maybe as a dedicated Physics (or however nvidia misspell it)

But the important thing is that is has a HDMI output.

Would my graphics suffer from plugging a crap card in not running SLI and just using it as a HDMI output?



I really have no idea about the effects of running multiple graphics, I've never had an SLI setup before ^-^

As I understand it, it will not hurt your performance so long as the dedicated PhysX card isn't super slow. A GTS 450, GTX 550, or GTX 460 will be good for you , and most (if not all) have HDMI output.

You can get a DVI->HDMI cable for a couple of quid, no need for an HDMI port if it has a DVI port.

Ha, great advice all round. +rep

Do have to ask though, does a DVI > HDMI converter carry audio? Because I plan to run my TV off it for watching DVDs and such, and I wont be anywhere near my speakers.

Also, I may end up running an extra GPU for the extra socket, unless of course I can use a splitter to duplicate the signal on my second screen. Both my second monitor and TV are 1080p so that might work nicely too.

No dvi is only video. You would need a hdmi only. But does sound even pass through the video card without some sort of pass through a sound card.? If not that would be irrelevant

Edit: sorry if that sounded rude or condiscending. Wasnt meant to be 7am here way to early

GTS450 would be ok. GTS250 is the ideal PhysX card, as you can get them super cheap. I wouldn't invest too much into one, though. Even cheap, the 480 can handle the load on its own for the most part.

The only game that really hurts without a dedicated card is Mafia 2. The APEX PhysX in that game are brutal.
In progress.

Get a gtx 260 ... great physX cards, are cheap as hell right now, and you can still find things like GTX200 heatsinks on ebay for cheap, so you can add it to your waterloop with a universal waterblock and salvage the waterblock whenever you don't need that phyX card anymore ... ie- when you get another GTX 480 for an epic SLI, lol. I'm running a GTX 480 + 260 physX right now actually and am extremely happy. Here is a comparison of some physX cards: http://media.bestofmicro.com/7/T/260.../mafia2_02.png

I have sound running through my other computer out the HDMI, but you're right, I do have to set that as the sound device for the computer. Unfortunately that's an AMD card

Not sure about the older cards, but I know fermi cards will run sound through dvi.

If you can afford it, I think the best option would be just get another 480 to double performance, that also has an HDMI output on it.

The 480's should support audio bitstreaming, meaning it can carry audio through HDMI without needing to connect a SPDIF cable to your card from your mobo.
